About

A bit about me

I’m a self-taught backend-focused web developer who loves transforming complex requirements into reliable, scalable systems. I specialize in designing clean database schemas, expressive REST APIs, and background processes that quietly power great user experiences.

When I’m not building production backends, I explore small side projects, contribute to open source, and share what I learn through practical code snippets and tutorials.
