Jordy de Koning
I'm co-founder and lead developer at Nysa, building DeFi RWA on Ondo assets — borrowing and lending against tokenized real-world assets. I've been shipping since 2014, when I co-founded Nefkon at university and started building web applications in Laravel and Django.
Alongside Nysa I lead development on Enable at Humanity Link, a platform NGOs use to fund beneficiaries on-chain and distribute aid transparently. Before that: protocol monitoring in Go with Prometheus and Grafana at Yala Labs, liquidator bot development, audit contests at Code4rena where I found several High and Medium severity issues in live protocols, and years of EVM dApp work in Dubai on .NET backends and Vue frontends.
Client work runs in parallel — integrated planning connecting Sherpaan orders with Trackpod delivery scheduling at Sfeer, AI-generated product specifications for Magento supplier imports, a cloud platform for gas installation maintenance documents at Raak Group, and booking software for barbers at Kappr.
I also run a home-lab honeynet on Proxmox for hands-on security research — that work ends up in the malware lab and the write-ups.
