Experience
Full Stack Developer, DRAPAI
2025 – Present
- Built DRAPAI, an AI virtual try-on app on the App Store and Google Play: a person photo and a garment image in, a photorealistic preview of the outfit out.
- Cross-platform mobile client with an on-device photo editor and a local wardrobe.
- Postgres backend with row-level security, social sign-in and server-side ownership checks before any generation runs.
- Generation pipeline modeled as a job lifecycle, with tokens held first and settled only when a job finishes.
- In-app token purchases and subscriptions on both stores, plus a bilingual (EN/TR) marketing site.
Backend Software Engineer (Contract), Age of Pirates Online
Jun 2026
- Integrated Xsolla payments into the game's website from scratch.
- Cut website load time by 30%: paginated the JSON responses, added preloading and set a ~2 MB transfer budget where the site used to load everything at once, and untangled deeply nested code.
- Cut server-side processing time by 30% by moving work off the main thread onto helper threads and running low-value job types less often.
- Hardened the server and game-server-to-website communication on selected API gateways: banning abusive IPs, filtering UDP floods, a CDN protection layer, and a baseline for access control, backups, monitoring, scheduled restarts and file permissions.
- Built an hourly report to the owner's Discord covering traffic, IP distribution, access attempts and attacks per endpoint.
