I've been building software since 2015, mostly with TypeScript, React, Node, Next.js, Python, and PHP. These days I work on full-stack products and AI systems with LLMs, agents, OpenAI, and Anthropic, with some web3 when it actually helps. I care about clear interfaces, boring reliability, fast feedback, and code that someone can maintain after the demo.
I've built full-stack and AI products across startups, agencies, web3 teams, and my own ventures.
