Open Source

I build software in the open. Every line of code, every design decision, every failed experiment ships publicly. Not because perfection is the goal, but because transparency is. Most of this site was generated, reviewed, and shipped with AI. The tools I build follow the same principle: functional first, refined iteratively, always accessible. From SFTP clients to DeFi protocols to the AI courses you can take right here. The source is yours to read, fork, and improve.
