Tomasz Kurcz

uint
Wrocław, Poland

Call me Tom! Polish techie. Rust developer. Enthusiastic about creating a fairer and nicer world. Highly independent. Decent cook.

Currently working on jtd-derive, which is JSON schemas optimized for codegen. Hoping to develop a better IDL for the Cosmos/CosmWasm ecosystem based on that work (loosely), but we'll see how that one goes.

Your sponsorship helps me keep spending time on open source projects like the above.

Also happy to take commissions for software. Let's talk!
