Project history
Freelance work for clients in Germany (Werklogik, DACH market) and Turkey (cancode), fully remote. Built Net Sport, a Flutter app for iOS, Android and web that records matches with IP cameras (live streams, replays, clips, venue booking), in use at 20+ football venues. Built a custom e-commerce platform from scratch (Next.js, Prisma, PostgreSQL) with FIFO stock, three VAT regimes, iyzico checkout and Cloudflare R2 media. Built an AI petition generator for lawyers (RAG over ChromaDB, Python/FastAPI, Next.js). Extended a field-workforce CRM used by 50+ staff. Built Node.js payment backends (Express/MariaDB payment bridge, crypto gateway). Run Linux infrastructure (Hetzner, Nginx, Docker, Vercel, Cloudflare). Fixed an indexing issue for a German training provider's site, which then earned 74K Google impressions in 3 months.
Develop the Coverz music platform's mobile app for iOS and Android with Flutter (Dart). Build and ship app features, handle web and mobile test automation with Playwright and Maestro, and track releases by reporting changes between production versions from GitHub history.
Delivered e-commerce platforms, CRM systems and corporate websites for company clients over 2+ years, working across frontend and backend. Built storefront, product-management and admin-panel features for e-commerce clients, from interface to API integration. Wrote end-to-end tests with Playwright to catch regressions before client releases.
