Rizzky
Software engineer. I build something for the web/mobile app, web3, chains, tools, security and agents/llms.
I have spent the last five years building software across the web platform, mobile, and creative coding. These days most of my work sits where web3, payments, distributed systems, tools and language models meet, mainly in Rust, Solidity, Elixir, Go and TypeScript.
