13+ years in full-stack development. I re-architected a Next.js-based Hotel PMS into a Turborepo monorepo at Rmos Yazılım (cutting CI/CD build time by 75%), built marketplace integration APIs for Amazon, Hepsiburada and Namshi at Modanisa, and worked on high-traffic product systems with MySQL, Elasticsearch and RabbitMQ at PTTAVM.
