Freelance
Flutter & Next.js
Developer

Okan Yalçın

I design and build mobile apps and web platforms, end to end — and stay until they're shipped. No hand-offs, no account managers. You talk to the person writing the code.

Flutter apps in the stores, Next.js sites in production, and the Python automation running quietly behind them. Based in Istanbul, working day-to-day with teams across Europe.
