I build web apps and AI automations with Bun, Node.js and TypeScript.
About me
I build full-stack web apps end to end. If an API has an endpoint, I'll integrate it. I work with TypeScript, Bun and Node.js, and occasionally venture into Python and PHP when there's no way around it. I'm currently looking for new work and opportunities. If you have a proposal, get in touch.
