Full-Stack Developer

TypeScript · React · Next.js · React Native · Node.js · PostgreSQL

Summary

Management Information Systems graduate from Istanbul Medipol University (100% English program, 85% scholarship). I build end-to-end web and mobile applications with TypeScript, React, Next.js and React Native; for real clients I have shipped fintech-adjacent solutions to production — live gold/currency price feeds and iyzico payment infrastructure — and my iOS app is live on the App Store. My MIS background lets me weigh technical decisions from a business-needs perspective; going forward, I aim to specialize in DevOps, cloud technologies and CI/CD, bringing development and operations together in end-to-end solutions.
