Systems_

Expert in designing and shipping high-performance backend systems that power real products. From distributed architectures to lean APIs, every line of code is written to last.

Whether it's rescuing a failing system, architecting from scratch, or scaling a platform to millions of requests — the backend is where the real work happens.

// ABOUT ME

Who I Am_

I'm a Full-Stack Software Engineer with a deep focus on backend systems. I care about clean architecture, reliable APIs, and software that doesn't break when things get serious.

My approach is engineering-first: understand the domain, design for scale, then build it right. I've worked across microservices, monoliths, and everything in between — and I know when to use which.

When I'm not deep in code, I'm reading about distributed systems, contributing to open source, or thinking about why most software is unnecessarily complex.
