Mobile App Developer

Hiring a mobile app developer is a long-term commitment. You're not just buying code — you're choosing a partner for the product's entire lifecycle. I work with founders, startups, and established businesses as their dedicated mobile developer, from MVP through scale-up and beyond.

What you get

1 Senior-level expertise

12 years in mobile. No junior passing through. You get the real thing, every meeting.

2 Founder-friendly approach

I speak plain language, challenge your assumptions, and push back when features won't serve your users.

3 Long-term partnership

My longest client is on year 4. I'm here for iteration, not just the first launch.

4 Fixed-scope or ongoing

MVP projects with a clear deliverable. Or continuous work on retainer. Whatever fits.

5 Full product thinking

UX, architecture, product strategy — not just code. I care about why you're building this.

Working together remotely

Most of my projects run remotely, and in practice that changes very little. We talk over video whenever you need to, not only at major milestones, and you can reach me with questions at any point during the project — I always answer.

Once we are working together, travelling to meet you on site can absolutely be arranged if your project calls for it. Travel costs are quoted separately, upfront and with no surprises.
