About Me
I'm a senior full-stack engineer with 13+ years of experience delivering enterprise products across fintech, transportation, IoT, hospitality, healthcare, telecommunications, public sector, education and R&D.
I combine C#/.NET and distributed backend engineering with Angular, React and TypeScript, contributing from architecture and API design through user-facing delivery, testing, deployment and production support. Owning both sides means the contract between them is something I design rather than negotiate.
My work sits where correctness gets expensive: transaction reliability and data consistency through idempotent processing, reconciliation and retry policies; throughput through SQL and index tuning, caching, asynchronous workflows and background jobs; and the observability to find out quickly when production disagrees with me.
For the past four years AI tooling has been part of how I deliver. I use Amazon Q, Codex and Claude for implementation, code exploration, debugging, refactoring, test generation and documentation, and everything they produce goes through the same review and tests as anything else.
Outside of code: I've been a Formula 1 fan since '98, I support Fenerbahçe, and there's almost always music playing in the background. Crime and thriller novels, anime and manga take up most of the rest.
