I’m Holger Hahn, a Solution Architect and Software Engineer with 15+ years of experience in digital banking, NFT, and Web3. I love turning messy, fragmented workflows into automated, compliant platforms and delivering production-grade systems. I’ve replaced legacy custody operations with modern, Fireblocks-based solutions and built audited smart contracts in Rust for staking and governance. I’m comfortable working with banks, NFT innovators, and startups alike, and I enjoy leading testing efforts from manual to CI-driven automation.
In addition to hands-on development (Python, Rust, Kubernetes, AWS, Node.js, Linux, Docker, CosmWasm), I’ve designed architectures that scale, integrated complex data flows, and guided teams to compliant, secure, and reliable implementations. My focus is on practical, end-to-end delivery that aligns business needs with technical realities.
