Who I am

Kritsada Lawan

// engineering mindsetI turn messy requirements into reliable systems — from the first React component to the last API response.

Hi, I'm Krit — a full stack developer with 10+ years of experience building web products from the ground up. Most days I move between React interfaces, Node.js services, database queries, and the edge cases that make production interesting.

I obsess over the details developers quietly care about: clear abstractions, fast feedback loops, useful logs, predictable APIs, and code that still makes sense six months later.
