Rockstar🎓
Top SchoolPeter Holloway is a software developer based in the Greater Oxford Area with 12 years of experience building reliable backend systems at Diamond Light Source. A Mathematics graduate from the University of Warwick, he applies strong analytical rigour to practical engineering problems, particularly around command-line tooling and terminal behaviour. He is an active open-source contributor, improving libraries such as JLine (enhancing completion, ANSI parsing and session-aware shells) and Atuin (robust handling of control characters in shell history), showing attention to edge-case stability and user-facing correctness. Comfortable working close to the metal of console I/O, he balances low-level protocol fixes with pragmatic improvements that directly improve developer and operator experience. Colleagues describe him as the sort of engineer who finds and fixes the tricky, easy-to-overlook bugs that make software feel polished.
