Summary
👤
Senior🎓
Top SchoolLev Israel is a seasoned technology leader and Chief Technical Officer with 25 years of experience building scalable cloud-native systems and data platforms, currently leading Engineering, Data, and Research at Sefaria. He steered Sefaria’s growth from a volunteer-built demo to an open-data library of nearly 381 million words and millions of interconnections, while launching AI/ML initiatives and migrating infrastructure to CI/CD on Kubernetes. Equally comfortable shipping front-end UX fixes in open-source repos as defining long-term strategy with boards, he blends hands-on engineering (notably UI/UX contributions to the Sefaria Project) with product-driven leadership. His background spans e-commerce scale challenges, enterprise data modeling, and mission-driven tech for Jewish learning, informed by studies in computer science, philosophy, and Jewish lore.
