Full Stack Developer specializing in web development — proficient in TypeScript/JavaScript, Python, and PHP, working across frameworks, libraries, APIs, and AIs.
I'm John Carlo, a full-stack developer based in the Philippines. I care about the whole surface of a product — the query that runs in 12ms, the button that feels right when you press it, the empty state nobody thought about.
I code so well that my compiler asks for autographs. It also yells at me in TypeScript, which keeps me humble.
These days I'm most at home in TypeScript, React/Next.js, and Node — with a growing obsession for WebGL and motion design.
