About

I hold a B.Sc. in Computer Engineering from Istanbul Gedik University. I build corporate websites, admin panels and multi-tenant web applications with Next.js and TypeScript.

Computer engineer and full stack developer

I worked as a full stack developer at Doğan Otomotiv and Waytogo. I have been freelancing since 2026: I built websites and admin panels for ACUSAS Kimya, Vortex Technik, Old City Media and Tuh'u Bahçe, while building my own product, QRMad.

Alongside the front end I write the back end: APIs with Express and MySQL, JWT authentication, rate limiting. I write tests with Vitest and Playwright, package applications with Docker and run CI with GitHub Actions.
