A crypto invoice that lives entirely in its URL. No backend, no database, no account — share a link, the payer connects a wallet and pays P2P on-chain. Built on VoidLayer, the open invoice codec (Rust + WASM) I wrote to make the format a standard, not a silo.

A Claude Code plugin that gives an LLM a persistent, interlinked knowledge base in Obsidian, based on Karpathy's LLM-Wiki pattern. 4 agents, 7 skills, and 27 scripts automate the capture / research / answer / audit loop. My most-starred open-source project.

I take on a small number of Web3 engagements at a time.
