I build open-source tools across the stack โ from Rust CLIs and Go services to AI SaaS and native Swift apps. Most of my work is scratching my own itch, then open-sourcing it. If you find it useful, even better.
๐ฏ Focus AI tooling ยท personal automation ยท web3 infra ยท systems programming
๐จ Style Ship small, iterate fast, polyglot by curiosity
๐ฑ Always Learning a new language / framework every quarter
