Summary
👤
Senior🎓
Top SchoolAlexander Viand is a Senior Software Engineer and researcher with 12 years of experience specializing in usable security, privacy-enhancing technologies, and making advanced cryptography practical for non-experts. He has a strong academic foundation from ETH Zürich (BSc, MSc, PhD) and a track record of translating research into engineering roles, including positions at Intel Labs, UC Berkeley, and a current role at Belfort. His work focuses on secure computation techniques—Fully Homomorphic Encryption, Secure Multi-Party Computation, and Zero-Knowledge Proofs—building systems, tools, and abstractions that lower the barrier to adoption. He combines rigorous research with hands-on product engineering, having moved between academia and industry to push HE from theory toward usable software. Based in Zurich, he’s notable for bridging deep cryptographic expertise with developer-facing tooling rather than purely theoretical contributions.
