How to Hire App Developer as a Non-Technical Founder – 2025
Know Your Tech Stack and Project Requirements
Before diving into hiring, it’s essential to understand your current technology setup and what your project demands. This groundwork helps pinpoint the exact skills and experience you’ll need in a developer.
Review Your Current Tech Stack
Start by taking a detailed inventory of your production environment. List all programming languages, frameworks, libraries, databases, and third-party services you’re using, along with their specific versions. According to Gartner, companies that perform a tech stack audit before scaling report 43% fewer production issues and onboard new team members 37% faster.
Visual aids like system architecture diagrams can make a big difference. These should map out your network topology, server configurations, data flows, and dependencies (including API integrations). Such documentation is invaluable for providing potential developers with a clear understanding of your environment.
For example, a fintech company reduced onboarding time by 60% and saved $400,000 by identifying critical system bottlenecks during a tech stack audit. The DevOps Research and Assessment (DORA) Report also highlights that high-performing engineering teams are 3.7 times more likely to conduct formal tech stack audits before expanding their teams.
Don’t stop at just the tools – analyze your development workflows as well. Document your branching strategies, code review processes, and approval workflows. Create a skills matrix that maps your team’s expertise against the technologies in use. This will help pinpoint areas where additional expertise is needed.
Once you’ve completed this audit, you’ll be in a strong position to define your project’s goals with clarity.
Set Clear Project Goals
Using insights from your tech audit, outline specific, measurable goals for your project. Start by defining the app’s primary purpose and target audience. Differentiate between essential features and those that are nice-to-have. Research competitors and market trends to see where your app can stand out.
Set timelines, budgets, and success metrics using the SMART framework. For instance, instead of saying, “finish the project quickly,” a more precise goal might be:
"Complete the iOS app development in 3.5 months, dedicating at least 10 hours daily, aiming to complete 33% of the project each month, with eight extra days reserved for unexpected challenges".
If your project involves sensitive data, outline security standards and compliance requirements upfront. For apps with complex technical needs, ensure these are clearly documented so developers can evaluate whether they can deliver.
Collaborate with stakeholders to refine these requirements, ensuring the app aligns with actual business needs. Conduct a risk assessment and plan for potential obstacles. Remember, clear communication is just as critical as technical expertise when building your team.
Plan for Growth and Future Updates
Think long-term when evaluating developers. Can they design an app that evolves with your business? With 85% of users favoring apps that receive monthly updates, maintaining a regular update cycle can boost user satisfaction and retention by up to 50%.
Ensure the developer can handle technology upgrades to keep your app running smoothly and securely. If you’re planning for market expansion – like localization or adding platforms – check whether the developer has experience in these areas. Studies show that 72% of users abandon apps that fail to improve over time.
Another key consideration is integration. Can the developer connect your app with other platforms or services to enhance functionality? A strong feedback loop is also essential – developers should be able to collect and act on user input for continuous improvement. Security is non-negotiable too. Apps that patch vulnerabilities within 24 hours see a 30% reduction in data breaches.
Lastly, platform-specific expertise is critical. Developers should be well-versed in current platform guidelines and ensure compatibility with the latest OS updates. With 47% of users expecting regular updates, setting realistic schedules for these improvements is essential.
Test Technical Skills and Experience
Once your project requirements are clear, the next step is to assess candidates’ technical skills. This ensures their expertise aligns with your current tech stack and team dynamics. It’s not just about knowing their skills on paper – it’s about seeing how they apply them in practice to meet your specific technology needs.
Run Technical Tests
The best way to gauge a developer’s abilities is through hands-on, practical tests that mimic actual challenges your team encounters. Instead of relying on abstract algorithm puzzles, focus on real-world problems. For instance, one financial services client reduced false positives by 68% by replacing algorithm-heavy interviews with domain-specific problem-solving sessions based on real production issues.
Start by reviewing candidates’ portfolios, such as their GitHub repositories. Look for well-organized code, clear documentation, and problem-solving strategies. Examining commit histories and code comments can reveal their attention to detail and coding habits.
Live coding sessions are another effective approach. These sessions allow you to observe how candidates debug, solve problems, and communicate their thought process. Ask them to write code in languages like Swift, Java, or Kotlin, and watch how they tackle challenges in real time. As Mark Nelson, a seasoned software engineer, explains:
"I’ve been surprised how effective a 5-minute code challenge can be in assessing software engineering candidates. Unsuccessful interviews fail faster. Discussion around the code, even this small amount, is enlightening".
Alternatively, consider take-home projects. These assignments give developers the chance to work on larger, more complex problems in a low-pressure environment. Just make sure the tasks reflect your business needs and allow room for creativity.
Automated coding platforms like HackerRank, CodeSignal, and LeetCode can also streamline your evaluation process. Customize tests to match your technical requirements. It’s worth noting that 85% of developers believe practical scenarios better demonstrate their skills than theoretical questions.
Once you’ve assessed their abilities, compare them to the specific technologies your project demands.
Match Skills to Your Technology Needs
To avoid costly mismatches, align candidates’ expertise with your project’s technological requirements. For example, since 71% of mobile developers specialize in either iOS or Android platforms, it’s essential to confirm their specialization matches your needs.
For iOS development, evaluate their proficiency in Swift, familiarity with iOS frameworks, and experience with Xcode. For Android development, focus on their skills in Kotlin or Java, knowledge of Android Studio, and understanding of Android-specific libraries and APIs. Kotlin, in particular, integrates smoothly with Android Studio and is a preferred language for Android development, while Swift provides excellent performance for iOS projects.
If your project involves cross-platform tools like React Native, Flutter, or Xamarin, test candidates on these frameworks. Additionally, ensure they are familiar with version control systems, testing frameworks, and deployment processes.
Backend and database integration skills are equally important for most mobile apps. Assess their experience with REST APIs, GraphQL, or other backend communication methods. Check their understanding of data persistence, caching strategies, and offline functionality.
To identify gaps or training needs, rate candidates’ expertise on a scale from 1 (basic familiarity) to 5 (expert-level proficiency) for each required technology.
Check Advanced Technology Experience
For projects requiring advanced features, such as AR/VR, 3D scanning, or Bluetooth integrations, you’ll need to dig deeper into candidates’ specialized expertise.
For AR/VR, evaluate their knowledge of gestures, voice control, spatial location, UI/UX design, and micro-interactions. Ask about their experience with tools like ARKit for iOS or ARCore for Android. For VR-specific projects, assess their familiarity with 3D environments, interaction animations, and sound effects.
When it comes to 3D scanning, inquire about their experience with tools like Artec Eva, Faro Focus, RealityCapture, or MeshLab. Check their understanding of scanning techniques such as structured light scanning, laser scanning, and photogrammetry. Also, ensure they can optimize 3D models for AR/VR by reducing polygon counts, optimizing textures, and applying Physically-Based Rendering (PBR) materials.
For Bluetooth and IoT integration, test their knowledge of wireless protocols, device pairing, and data transmission. Look for expertise in Bluetooth Low Energy (BLE), mesh networking, and security measures to ensure connection reliability and optimize battery usage.
Security and compliance are critical for advanced features, especially in industries like healthcare or finance. Verify that candidates understand data encryption, secure storage, and privacy regulations. If your app involves healthcare or financial data, ensure they are familiar with standards like HIPAA or PCI DSS.
To confirm these specialized skills, use practical demos and in-depth discussions about real-world implementation challenges. This approach will help you identify candidates who can tackle your project’s unique demands.
Check Team Fit and Work Style Match
Technical skills are only part of the equation when it comes to hiring. A poor fit with the team can disrupt workflows and lower productivity. In fact, 86% of employees and executives say that workplace failures stem from poor collaboration or communication. This makes assessing team fit just as important as evaluating technical expertise.
This is especially critical in mobile development, where 75% of cross-functional teams struggle to function effectively. Mobile developers typically work alongside designers, product managers, QA testers, and backend developers. To succeed, they need to communicate clearly, align with your team’s processes, and collaborate seamlessly across departments.
Test Team Chemistry
Once you’ve confirmed technical qualifications, focus on how well candidates mesh with your team’s dynamics. Chemistry isn’t just about getting along – it’s about finding someone who aligns with your team’s values, communicates effectively, and contributes positively to the environment.
Professionalism is key. During interviews, assess both their technical skills and their ability to collaborate. For instance, ask candidates to describe a time they made a mistake on a project. Those who take responsibility, explain how they resolved the issue, and reflect on what they learned demonstrate accountability – an essential quality for team players.
Strong communication skills are also a must. Pay attention to how candidates explain technical concepts during interviews. Are they clear and concise? Can they simplify complex ideas for others? This matters because 79% of project failures are linked to poor communication.
Adaptability is another critical trait, especially in agile environments. Ask about their experience with methodologies like Scrum or Kanban, and how they’ve handled changing requirements. Can they switch between tools and workflows as needed? Flexibility is essential since no two projects are exactly alike.
Finally, prioritize candidates who show kindness and a willingness to support others. Developers who genuinely want to help solve problems, rather than just showcasing their own skills, contribute to a healthier team dynamic.
Check Work Process Fit
To gauge whether a candidate fits your work processes, consider practical assessments that mimic real-world scenarios. For example, if your team uses agile practices like daily stand-ups – which can boost productivity by 20% – evaluate how candidates adapt to these workflows.
Trial projects or pair programming sessions are excellent ways to see how candidates approach tasks, communicate with team members, and respond to feedback. During these sessions, observe whether they ask thoughtful questions, explain their reasoning clearly, and handle constructive criticism well.
Group interviews with 2-3 team members can also reveal a lot. Watch how the candidate interacts in a group setting. Do they communicate effectively, listen actively, and contribute constructively? Some people excel in one-on-one conversations but struggle in group dynamics, while others may dominate discussions or fail to consider others’ ideas.
You’ll also want to see how quickly they adapt to your tools and systems. If your team relies on platforms like Jira, Slack, or GitHub, test their comfort level with these tools. Teams using project management platforms often deliver projects 30% faster, but this only works if everyone can navigate the systems effectively.
Don’t overlook their feedback style. Teams that establish regular feedback intervals – such as weekly reviews – can see a 30% improvement in efficiency. Ask candidates how they give and receive feedback. Look for those who can offer constructive criticism without being overly harsh and who are open to receiving input without becoming defensive.
Make Sure They Work Well Across Teams
Beyond technical skills and process fit, it’s crucial to ensure that candidates can collaborate across departments. Mobile developers rarely work in isolation. They need to coordinate with designers on user interfaces, backend developers on APIs, and product managers on feature requirements. Companies that emphasize interdepartmental collaboration report a 15% increase in innovation output.
Assess their ability to translate technical concepts for non-technical stakeholders. Can they explain technical challenges without resorting to jargon? Can they offer alternative solutions when initial ideas aren’t feasible? These skills are critical when working with designers, product managers, and executives.
Look for candidates who show initiative and enthusiasm for stepping outside their primary role. For example, have they ever participated in user testing, contributed to design discussions, or assisted with deployment tasks? A willingness to go beyond their core responsibilities signals a strong team player.
Cultural awareness is increasingly important, especially in diverse teams. Teams that are culturally aware tend to collaborate 20% more effectively. Ask candidates about their experience working with distributed teams or colleagues from different backgrounds. How do they adjust their communication style to suit different audiences?
Finally, test their conflict resolution skills. Disagreements are inevitable when departments have competing priorities. Strong candidates can share examples of how they’ve resolved conflicts or found compromises that worked for everyone. Look for evidence of active listening and an ability to find common ground.
At Sidekick Interactive, we’ve seen firsthand how the right developer can bridge gaps between technical and business teams.

Check Security, Compliance, and Maintenance Skills
After evaluating technical and teamwork abilities, it’s crucial to assess a developer’s understanding of security, compliance, and maintenance. These areas are non-negotiable, especially when you consider that 76% of mobile apps have at least one serious security vulnerability. A developer who prioritizes security and is prepared to maintain and update your app over time will help ensure it stays functional, safe, and aligned with evolving standards.
This is particularly critical for businesses handling sensitive information. Healthcare organizations must avoid HIPAA violations, financial services need to adhere to PCI DSS standards, and companies dealing with EU customers must comply with GDPR. A single oversight in security or compliance could lead to hefty fines, lawsuits, and long-lasting damage to your reputation.
Test Industry Compliance Knowledge
Every industry comes with its own compliance demands, and your developer must be familiar with those specific to your business. A Ponemon Institute study found that 70% of organizations suffer data breaches due to non-compliance. This makes it essential to evaluate a candidate’s knowledge in this area.
Identify the standards relevant to your industry. For example:
- Healthcare: HIPAA compliance ensures secure handling of personal health information.
- E-commerce: PCI DSS compliance is mandatory for secure payment processing.
- California-based services: CCPA compliance protects data rights for California residents.
- EU customers: GDPR compliance governs data handling and privacy.
| Compliance Standard | Industry | Key Requirements | Evaluation Method |
|---|---|---|---|
| GDPR | Any app handling EU citizen data | User consent, data access/deletion rights, breach notification | Ask about data minimization principles and user consent processes |
| HIPAA | Healthcare | PHI encryption, access controls, audit logging | Test knowledge of secure data storage and transmission practices |
| PCI DSS | E-commerce, Finance | Secure payment handling, network security, monitoring | Ask about data masking, tokenization, and secure coding practices |
| CCPA | Apps serving California residents | Right to know, delete, and opt-out provisions | Test understanding of data collection and sales practices |
During interviews, ask candidates to explain compliance measures relevant to your business. For GDPR, they should discuss data minimization and user consent processes. HIPAA-related questions should cover encryption and access controls for personal health information. Look for detailed, experience-backed answers – not vague generalities.
Since employee misunderstandings account for 50% of compliance breaches, it’s critical to confirm that your developer fully understands these principles. Ask them to walk through real-world scenarios where they’d apply compliance measures to your app. Strong candidates will ask thoughtful questions about your data practices and suggest tailored technical solutions.
Check App Security Knowledge
A developer’s grasp of security measures is just as important. They should be well-versed in encryption techniques, particularly AES-256 encryption for protecting sensitive data both in transit and at rest. Ask about their experience with secure authentication approaches like multi-factor authentication and biometric login. Strong candidates will also mention token-based authentication, secure API communication, and input validation.
"Mobile app security isn’t some trendy buzzword to throw around at industry events… It’s the silent shield between your users’ valuable data and the shady fellas lurking in cyberspace. And trust me, in 2025, these fellas are becoming more and more creative minute after minute!" – Sultan Hanif, Tekrevol
Evaluate their knowledge of common security threats such as insecure data storage, weak authentication, code injection attacks, and reverse engineering. Ask how they would mitigate these risks in your app. Look for candidates who bring up security testing techniques like penetration testing and code analysis.
Platform-specific security expertise is also essential. Android developers should understand the risks associated with sideloading and third-party app stores, while iOS developers need to address jailbreaking vulnerabilities. They should also know how security updates function on each platform and why timely updates are crucial.
Additionally, don’t overlook API security. Your developer should know how to implement strong API authentication, rate limiting, and input validation. They should also understand the importance of secure server-side practices, such as firewalls and intrusion detection systems.
Check Maintenance and Update Experience
Developing an app is just the beginning. 90% of users abandon apps due to performance issues, and 53% leave apps that take more than 3 seconds to load. This makes a developer’s maintenance experience critical for long-term success.
Ask candidates about their experience with different types of maintenance:
- Corrective: Fixing bugs.
- Adaptive: Updating for new operating systems.
- Perfective: Improving performance.
- Preventive: Regular security updates.
- Emergency: Handling urgent fixes.
A strong developer will see maintenance as an ongoing process of improvement rather than an afterthought. Discuss their familiarity with performance monitoring tools like Firebase and New Relic. They should explain which metrics they track – such as crash reports or user behavior data – and how they prioritize fixes and enhancements.
Security maintenance is especially vital, as over 40% of cyberattacks target mobile apps with outdated security. Ask about their experience with regular security updates, monitoring for vulnerabilities, and responding proactively to threats.
Finally, don’t forget about app store management. Developers should know the submission and update processes for both iOS and Android platforms. Ask about their experience with app store guidelines, handling rejections, and addressing compliance issues.
At Sidekick Interactive, we’ve seen firsthand how proper maintenance can determine an app’s success. Our developers work with clients in sensitive industries like healthcare and finance, ensuring apps remain secure, functional, and user-friendly over time.
