##about01

Engineer working on web and mobile products, mostly in TypeScript. Interested in staying current with the toolchain without letting it become the job — the deliverable is a product that loads fast, ships often, and does not page anyone at night.

Graduated in Computer Engineering from İstanbul Teknik Üniversitesi. Since then: eight roles across agencies, startups and product teams in İstanbul, Lisbon and Delaware.

Senior Software Engineer— since 2026.01
  • — Lead engineer and technical owner of a multi-brand sports platform: five clubs, each with a mobile app, admin dashboard and website.
  • — Architected the shared package platform all club apps build on: layered monorepo, dependency and versioning policy, 9 packages at 1.0.0 across 4 React Native apps.
  • — Owner of the flagship app (1M+ registered, 40–50k monthly active users): architecture, performance and release strategy.
  • — Set a measure-first performance practice: tab revisit 319 → 45 ms, first Android tab visits 3–4× faster, ~20% lower memory use.
  • — Designed one delivery model for every brand: shared CI/CD, environments and release pipelines; halved Android build time and cut costs.
  • — Architected the content team's admin dashboard from scratch.
