Rockstar🎓
Top SchoolHannes Furmans is a CTO and co-founder with six years of hands-on experience building decentralized systems, embedded ML, and AI-powered robotics. Currently studying Computer Science at ETH Zürich, he’s an active Rust pro who contributed AutoNATv2 work to rust-libp2p under a Filecoin Foundation grant and has fixed and modernized core libp2p modules used widely across Web3. He spearheaded backend and embedded development early in his career at Feldfreude, developed an uncommon end-to-end encrypted messaging schema (Dione), and deployed ML models to memory-constrained devices at Weber-Hydraulik. Hannes blends product-focused leadership—now at Stillwind and formerly leading a project for a major German automaker—with deep protocol and systems expertise. He regularly prototypes generative-AI and robotics applications, many available on GitHub, and follows the evolution of Rust and its community closely. A practical tinkerer with startup and grant-backed open-source credentials, he excels at turning research-grade ideas into deployable systems.
