01Profile

Full-stack engineer specializing in React, Node.js and AI-powered web systems. I built a self-evolving website intelligence platform — connecting source code, runtime behavior, performance and external signals to find optimization opportunities. I care about systems that are engineered deeply and feel effortless on the surface.
