About Me

Who I Am

I'm a software engineer with 5+ years of experience building products that scale. I specialize in backend systems and cloud architecture, but I'm equally comfortable crafting polished frontend experiences.

I believe great software is both technically excellent and deeply human — it should be fast, reliable, and a joy to use. I bring that philosophy to every line of code I write.

When I'm not engineering, I'm contributing to open source projects, writing technical articles, or exploring new frameworks and paradigms.
