I build web apps and AI automations with Bun, Node.js and TypeScript.
About me
I'm a full-stack developer, 20 years old, focused on shipping web apps and automations with Bun, Node.js and TypeScript. I occasionally venture into Python and PHP.
I specialize in AI automation — if an API has an endpoint, I'll integrate it. I lean heavily on Claude Code and Codex in my daily workflow.
I'm not actively taking on work right now, but if you have an interesting proposal, drop me a line.
