Rockstar🎓
Top SchoolGary Benattar is a Principal Software Engineer specializing in agentic AI and cloud architectures, with eight years of experience building high-impact systems at AWS and Amazon. A former co-founder and engineering lead at ZenGo, he helped create the world's first keyless crypto wallet and contributed core Rust implementations for threshold ECDSA and Schnorr-based proofs. Known for shipping rapid, production-ready proofs-of-concept end-to-end, he combines deep cryptography and back-end expertise with operational mastery of AWS services. He has led cross-functional teams and introduced R&D-wide quality and delivery improvements at scale. Based in Israel and a graduate with highest honors from Pierre and Marie Curie University, he pairs entrepreneurial grit with persistent delivery and a penchant for tackling hard infrastructure and security challenges. An avid grappler, he brings the same discipline from Brazilian jiu-jitsu to engineering execution.
