Rockstar🎓
Top SchoolJulio López is a software engineer and founding engineer at Kasten with 11 years of experience building cloud-native, data management and backup systems from day zero to production. He holds a Ph.D. from Carnegie Mellon and brings deep expertise in scalable, concurrent systems—work that spans research-grade parallel I/O at CMU to production metadata servers and distributed storage at Maginatics/Dell EMC. At Kasten/Veeam he co-created core data mover functionality and contributes to CNCF projects like Kanister, while as a Kopia PMC member he has improved profiling, snapshotting and garbage collection for a widely used cross-platform backup tool. Julio blends academic rigor with hands-on engineering, focusing on performance, reliability and maintainability, and he routinely refactors core subsystems to make them easier to profile and extend. Based in the San Francisco Bay Area, he’s an active open-source contributor who prefers solving hard infrastructure problems over surface-level features.
