◈ About Me

I'm a Full-Stack and Backend Engineer who obsesses over system design, clean architecture, and developer experience. I don't just ship features — I build foundations that scale.

My backend work revolves around Go and .NET 8, designing RESTful APIs and event-driven services that are both performant and maintainable. On the frontend, I craft polished UIs with Next.js and TypeScript — always with UX and performance in mind.


Engineering values:

▸  Architecture over hacks   — design before writing a line
▸  Clean code                — readable, testable, built to last
▸  Ship fast                 — CI/CD, containers, automated
▸  Iterate openly            — feedback loops shape better engineers
