Building robust backend systems and clean APIs.

Focused on distributed systems, concurrency, and scalable architecture.

About

I'm a backend developer with a strong focus on building reliable, scalable systems using Go. I enjoy designing clean APIs, working with distributed architectures, and solving complex engineering challenges.

My approach to software development is rooted in clean architecture principles — writing code that is maintainable, testable, and built to last. I believe great backend systems should be invisible: fast, reliable, and effortlessly scalable.

Currently pursuing my undergraduate degree while actively building real-world systems and contributing to open-source projects.
