Senior Full-Stack Architect

15+ years engineering production-ready platforms across web, mobile and hardware-integrated environments — from RFID logistics to high-traffic SaaS.

Based in İzmir, I engineer production-ready platforms that span web, mobile, and hardware-integrated environments. My core strength lies in backend architecture and end-to-end full-stack development, building resilient, scalable systems with Laravel, NestJS, Next.js, React, and React Native.

From complex RFID-driven logistics software to high-traffic SaaS infrastructures, I apply Domain-Driven Design (DDD) and clean-code principles to keep every system scalable, maintainable, and built to last.
