Summary
🤩
Rockstar🎓
Top SchoolTom Mewett is a versatile software engineer with nine years’ experience across embedded systems, backend services, and build & integration work, now based in Cambridge. He combines hands-on firmware contributions—such as improving Raspberry Pi bootloaders, USB booting, VL805 updates and adding secure boot/network install capabilities—with leadership in commercial roles from PlayStation to Codethink. Comfortable across the full software lifecycle, Tom moves between client-facing work, internal design and research, and is confident presenting to technical and non-technical audiences. A fast analytical learner, he repeatedly ships low-level fixes that have outsized impact on device reliability and developer tooling. His career blends contractor agility (running Orthographics) with senior engineering at game and platform companies, showing both breadth and depth. Non-obvious: he has direct experience improving mass-storage and EEPROM tooling used by the widely adopted Raspberry Pi platform, demonstrating production-grade embedded expertise.
