About

I'm a Backend and Generative AI Engineer passionate about building scalable systems and intelligent AI applications. I enjoy solving complex engineering problems and turning slow, inefficient systems into fast, scalable solutions.

Outside of work, I enjoy building side projects, participating in hackathons, and expressing creativity through piano and video editing.
