Rockstar🎓
Top SchoolAlistair O'Neill is a seasoned technology leader and hands-on engineer with six years of commercial experience, currently serving as Vice President of Technology at Citi. Trained in mathematics at the University of Cambridge, he began his career building safety-critical medical software at TPP, where high-pressure, zero-error requirements shaped his disciplined approach to security and reliability. Since 2018 he has led freelance and startup projects—ranging from a virtual vet clinic for the Royal Veterinary College to a location-based marketplace as chief technical architect—bringing full-stack ownership of architecture, backend systems and Android frontends. He enjoys exploratory hardware-software integration and creative user experiences, exemplified by a hedgehog-to-video-game Twitch ecosystem that combined computer vision, Arduino controls and streaming. Comfortable switching between enterprise governance and rapid prototype development, he pairs analytical rigor with a taste for playful, multidisciplinary experiments.
