Hi, I'm Wouter Schreuders
I PROTOTYPE WITH REAL APIs SO ENGINEERING SHIPS WHAT WORKS.
Approach
I prototype with real APIs and live data, so engineering picks up tools that have already met reality. At NFTfi I shipped a custom D3 bubble chart from concept to validated lender tool in five days. At Hound & Halo I built a consistent cast of 3D characters using a handful of prompt-engineering rules. The case studies below cover both.
Underneath: 20+ years across Web3, fintech, and enterprise. Founding team member and equity stakeholder at a leading NFT lending protocol. Deep DeFi fluency: lending, staking, token incentives, governance. A record of leading design teams, engaging C-suite stakeholders, and building design systems from scratch.
