Fullstack Engineer
I'm a full-stack engineer who's spent 4.5 years building products people actually use, from enterprise clients at Insider to the HarmonyOS Gallery app at Huawei, used by 10M+ people. I work across the stack, from React frontends to Node.js APIs and the databases behind them.

About
A bit about me
I like building products end-to-end: accessible, tested interfaces backed by APIs and databases that hold up when the data gets heavy. I work with React, TypeScript, Next.js, and Node.js, and what I enjoy most is owning a feature across the whole stack instead of just one slice of it.
My Civil Engineering background at METU is where I learned to approach problems in a structured, methodical way.
