Marc‑Aurele Besner
I design and build decentralized apps, smart contracts, SDKs, open source tools, block explorers, and AI agents. I'm familiar with decentralized systems for encryption and data storage.
With 5+ years shipping Web3 products—from smart contracts and SDKs to block explorers and AI agents—I bring both technical depth and the ability to translate complex systems into developer‑friendly tools. Currently exploring AI‑assisted DeFi agents and decentralized infrastructure. Let's connect!
