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.
