Blockchain Engineer & CTO at Veggies Labs
Geneva, Geneva, Switzerland
Summary
👤
Senior🎓
Top SchoolLéo Fasano is a Blockchain Engineer and CTO based in Geneva with 9+ years of EVM-focused protocol security and full-stack blockchain experience. He has progressed from full-stack web roles into specialized blockchain engineering across startups and product-facing teams, most recently leading technical strategy at Veggies Labs after stints at Holograph, RA2 TECH, and Nested. Known for marrying security-first protocol development with practical product delivery, he bridges smart contract auditing, tooling, and architecture. His background in computer science and sustained hands-on work suggests he’s as comfortable debugging low-level EVM quirks as driving team-level technical decisions. An understated strength is his continuity across projects—from early fullstack builds to CTO responsibilities—giving him both implementation depth and leadership perspective.
