His work spans distributed databases, conflict-free replicated data types, and seamless SQL engines that combine OLTP semantics with object storage performance. Guy pairs academic rigor (PhD research and TA roles in operating systems) with practical engineering, having taught core OS and software design courses while mentoring internal Spark SQL adopters. He holds an MBA and a BSc in Electrical and Electronics Engineering, reflecting a rare combination of technical depth and business perspective that informs his system-design decisions.
