Sahin B.

I build web and mobile apps with React, React Native and TypeScript, and I've been doing it professionally for over 7 years. Most of my work is on the frontend and mobile side: starting new apps, or joining an existing codebase and moving it forward. I have a BSc in Computer Engineering and I've worked across many stacks and industries, so I read unfamiliar codebases quickly and pick up new libraries or tools when a project needs them. Recent work: - An internal operations dashboard for an algorithmic trading platform, as the main frontend developer (React 19, TypeScript, RTK Query) - Safr, a travel booking marketplace in Morocco: Stripe booking and payments, and the web side of an AI travel assistant - Dezor, a React Native media app for phones, TVs and desktop, as a core developer: downloads, Chromecast, Android TV and the in-app browser - Two React Native apps for a workspace booking platform, published to the App Store and Google Play What I can help with: - React Native apps: new builds, new features, upgrades, App Store and Google Play releases, in-app purchases, push notifications - React and Next.js web apps: dashboards, booking and payment flows, multi-language and RTL support - Taking over an existing project, fixing bugs and cleaning up the code - Working with REST APIs, WebSockets and Stripe, and Node.js/Express when the project needs it I keep you updated, ask questions early instead of guessing, and I don't disappear once work starts. I use Claude Code and Codex every day to move faster, and I review everything they write before it reaches you. Available 30+ hours a week, US hours are fine, and I'm open to long-term work.
