Backend & web3 engineer working with Go, Rust & React in the finance world — shipping dapps, smart contracts, and AI agents on-chain. I write to make complex things feel simple — most recently about Go 1.27 Recap, Go 1.26 Recap, and Go 1.25 Recap.
“Easily one of the best people I have worked with.”

Made Simple.
A few mental models I keep coming back to when I want something complex to feel more understandable.
