About

Who I am

I'm a Full-Stack Software Developer with hands-on experience across the entire stack — from pixel-perfect React frontends to high-throughput distributed backends.

I care about clean architecture, performance, and maintainability. Whether it's designing a system for millions of daily requests or building a smooth UI component, I bring the same attention to quality and production-readiness.
