Summary
🤩
Rockstar🎓
Top SchoolJohn Floren is a systems-minded software engineer with 16 years of experience building low-level and embedded systems, now serving as a Fellow at Gravwell after eight years as a senior engineer there. He combines deep OS and hardware expertise—Go and C specialist skills, embedded hardware prototyping, and low-level Android hacking—with practical experience in large-scale PC emulation and build automation. At Harvey-OS he helped architect and automate the distributed OS build and CI, demonstrating a knack for bridging system design and engineering operations. Prior work at Sandia National Labs underscores his background in mission-driven, high-assurance projects, and his academic training (B.S./M.S. in Computer Engineering, RIT) grounds his hands-on approach. Equally comfortable on a breadboard or in a containerized CI workflow, he’s driven by a belief that operating systems and wearable/space-facing hardware are ripe for reinvention.
