    "summary": "Blockchain engineer with 7 years in software development and 5 years in blockchain, including the design, launch and ongoing maintenance of a production Cosmos SDK Layer 1. As CTO and co-founder of Safrochain, I built the chain, its custom modules, its genesis and validator coordination, its indexer, explorer and multisig tooling, and I ship the core upgrades that keep it running. I also lead Zunia, a self-custody multi-chain Cosmos wallet covering 262 chains, and serve as a Developer Advocate at Intersect for the Cardano ecosystem. I work best in small, senior, remote teams that own a chain end to end.",
