Summary
👤
Senior🎓
Top SchoolRafael Belchior is a Research Engineer and Senior Software Engineer with a PhD in Blockchain and over a decade of experience building secure, distributed systems from research prototypes to production. Based in Portugal, he combines academic rigor (IST, MIT visiting researcher via a Fulbright) with hands-on engineering at organizations like LF Decentralized Trust and Blockdaemon. He maintains and contributes to prominent open-source projects such as Hyperledger Cacti, where he improved Fabric private-data support and test infrastructure for multiple ledgers, reflecting deep interoperability expertise. Rafael has a strong R&D pedigree—postdoc and doctoral work at INESC‑ID, teaching experience as an invited assistant professor, and a track record mentoring R&D teams. He blends backend and DevOps skills to ship reliable, auditable systems and often bridges the gap between formal research and practical blockchain deployments. A less obvious strength is his repeated role as a connector: coordinating documentation, tooling, and testing across complex multi-ledger ecosystems to accelerate adoption.
