About

I'm a backend engineer who takes problems seriously.
300+ LeetCode problems, production deployments, and a long streak of building things that actually work — not just compile.

I contribute to open source backend projects and actively study real-world system design — reading codebases, understanding architectural decisions, and learning how production systems are actually structured.
