About

Full Stack Engineer with ~5 years of experience. I like solving real engineering problems — scaling, cost-cutting, robustness — not just algorithm puzzles. I write code in Python, JavaScript (Node), Go, and C++, and I enjoy automating the stuff that wastes time. I care about clean code, strong systems, and practical solutions.
