HowtoVetaFreelanceDeveloper'sPortfolioBeforeYouHire

A GitHub repository or a portfolio screenshot is far less convincing than a live App Store link, a working production URL, or a documented case study with real, specific detail — architecture decisions, technologies used, and concrete outcomes. Anyone can show code; shipping something to production, keeping it running, and being able to speak specifically about real trade-offs made along the way is a meaningfully different signal.

Ask about the case studies that are most similar to your project specifically, rather than accepting a general "I've done projects like this" — the more specific the answer, the more likely the experience is genuine.

You don't need to be technical yourself to ask a good vetting question — ask what state management approach they'd use for your mobile app, or how they'd handle a specific data relationship in your product, and evaluate whether the answer is specific and confident or vague and generic. A developer with real production experience should be able to explain their reasoning in plain language, not just cite a technology name.

For offline-first, real-time, or other technically demanding requirements specifically, ask directly whether they've shipped that kind of feature before — this is exactly the kind of requirement where prior hands-on experience matters most.

If references are available, a short conversation with a past client about responsiveness and reliability is worth the time — technical skill without reliable communication is a common source of failed engagements. Pay attention to how they communicate during the scoping process itself: the quality of questions they ask about your project is often the best available signal of what working together will actually be like.
