What I'm looking for

I'm looking to own end-to-end product delivery, from backend architecture and payments to web, mobile, infrastructure, and production release.

I’m a full-stack engineer based in Istanbul, and since June 2026 I have been the sole developer behind Patimania, a pet-services marketplace now at 1,383 commits. I own it end to end: a NestJS 11 + Prisma 6 + PostgreSQL API with 52 data models across 26 modules, a Next.js 15 / React 19 web client, a React Native 0.86 + Expo 57 mobile app for iOS and Android, and an iyzico sub-merchant payment flow covering ledger, payout and commission handling.

The infrastructure is mine too: Docker Compose, nginx, MinIO and pg-boss behind four GitHub Actions pipelines and more than 20 end-to-end test suites. Before Patimania I ran POS, barcode, scale and online-sales integrations for a multi-branch retail chain, and I have six years of C# and Unity behind me from studio and self-published work. I work remotely from GMT+3 and I’m looking for an individual-contributor role where I can keep shipping product end to end.
