About

A bit about me

I like frontend work that goes beyond the surface: accessible, tested, and fast even when the data gets heavy. I work with React, TypeScript, and Next.js, and I'm comfortable reaching into the backend when a project needs it.

My Civil Engineering background at METU is where I learned to approach problems in a structured, methodical way.
