Hard to break.
Easy to use.
I'm Jordy. Co-founder and lead developer at Nysa, building DeFi RWA on Ondo assets. Before that: protocol monitoring in Go, EVM dApps, and audit contests on live protocols. I think like an attacker the whole way through.

What I build with
The honest version — what's open on my machine most days, what I pick up when a project calls for it, and what I'm still getting comfortable with.
