About Me

Interested in Designing Solid, Reliable Systems

I’m a full-stack developer who enjoys designing solid systems, building reliable backends, and planning databases that make sense. I like thinking through how applications are structured and solving problems through code.

I’m always learning through personal projects that challenge my technical skills and creativity, exploring new approaches and gradually improving how I build systems.

Outside of coding, I enjoy peaceful environments and having a fun time with friends. I believe being kind to others is a choice worth making.
