What I build
I'm an independent developer. I ship open-source tools and do smart-contract security research — most of it built in the open.

My current focus is FetchMux: a self-hosted gateway between AI agents and web-search providers (Brave, Tavily, Exa, Firecrawl). Your agent sends one request; FetchMux enforces a hard cost ceiling and deadline before the call, picks a provider, falls back safely on failure, and returns a receipt showing exactly what it did and what it cost. Apache-2.0, free to self-host.

Alongside it I publish security research and smaller tools — an audit portfolio, a bug-bounty operator kit, and a from-scratch proof-of-work coin experiment.

Why sponsor
I give this work away because good infrastructure and honest security research should be free. Sponsorship is what lets me keep maintaining it and starting new things instead of walling it off. If something I built saved you time, money, or a headache, a sponsorship keeps it going.
