James Whitfield-Hayes

With a PhD in Computer Science from Imperial College London and twenty years of experience spanning Google, two venture-backed startups, and academia, I offer tutoring at the highest level. My career has taken me from low-level systems programming to leading machine learning teams of fifteen engineers.

At Imperial, I lectured on algorithms and distributed systems for six years. At Google, I worked on search infrastructure and large-scale data processing. As CTO of a fintech startup, I built the entire technical platform from scratch. This breadth of experience means I can teach almost any computing topic with authority and practical insight.

I take on a small number of private students each year — typically PhD candidates, senior developers preparing for FAANG interviews, or entrepreneurs building their first technical product. My sessions are intensive, challenging, and transformative. I do not believe in hand-holding; I believe in building genuine understanding that lasts.

My hourly rate reflects two decades of accumulated expertise. If you are serious about reaching the highest level in computer science, I can get you there faster than anyone else.
