About Me
I'm a full-stack developer who feels most at home in the backend.
I build backend systems with Python and Django - focusing on clean APIs, scalable architecture, and code that's built to last. On the frontend, I work with TypeScript, Next.Js, React, and Astro to create fast, modern interfaces that remain simple and maintainable.
Philosophy
I care about writing code that's clean, practical, and built to last - not just to impress.
Interests
I'm interested in backend engineering, system design, AI engineering, open-source development, developer tools, and building practical software products.
