C. Başar Özcan
Senior Fullstack Developer — Berlin, Germany
I build engaging, user-friendly web interfaces and the scalable services behind them. My focus is shipping features end to end — translating design mockups into responsive UIs, modeling the data, and writing the Node.js APIs that tie it all together.
Most recently at JUMiNGO and Virail, I've led migrations from legacy JavaScript to TypeScript, refactored critical features into modern, lean codebases, and shipped A/B-tested UX changes that moved real metrics — including a 31% lift in traffic to the ticket booking page on a metasearch platform serving 40M+ users across 30+ countries.
Outside of client work I co-founded Dugunmuvar (a wedding-planning SaaS), run Cheaphouz (a Berlin housing notifier), and tinker with native macOS apps and recent LLM tooling. I care about correctness, performance, and the long-term maintainability of whatever ships.
