I’m a senior full-stack engineer based in Istanbul with 5+ years of hands-on experience building high-reliability systems for fintech, real-time trading, and marketplace platforms. I’ve shipped real-time trading and web products serving millions of end users, partnering across teams and frameworks (React, Angular/Vue, TypeScript) while implementing robust backend services with Node.js and API integrations. I enjoy working on systems that require both performance and correctness—real-time data pipelines (WebSockets), secure auth and RBAC, idempotent event processing, and payment/webhook flows. In recent work, I’ve led end-to-end delivery of cross-platform mobile/commerce experiences, integrated multiple third-party APIs, set up CI/CD, and used AI coding tools like Cursor and Claude while keeping security-critical logic carefully reviewed.…I’m a senior full-stack engineer based in Istanbul with 5+ years of hands-on experience building high-reliability systems for fintech, real-time trading, and marketplace platforms.
