About

Currently building something that focuses on delivering human authenticity in communication, while still enhancing it with AI. I was OpenAI's first hire for the London office, having been the technical lead and a research manager for the Human Data team. We collected data that trained and improved model capabilities - we dramatically improved GPT-4o, around evals, accents quality, image generation performance, and safety. Also 10+ years at Facebook. I built the first version of activity log, and early versions of the privacy selector. I revamped huge chunks of the chat and messages UI (https://techcrunch.com/2012/08/22/facebook-redesigns-messages-with-side-by-side-layout/). Also led multiple VR teams: Oculus Avatars, Horizon Workrooms (https://forwork.meta.com/gb/horizon-workrooms/).

Are the best startups built on boring problems?

I came to exactly the same conclusion that real startup ideas often come from simple and boring problems. From my own experience: I spent three years on a startup that was supposed to revolutionize online education, but in the end it had 0 users. Now I ve just started solving a simple problem for home appliance repair technicians and immediately got my first paying users on a very rough MVP.

Thanks for #1 - here's what's next

Hey everyone - we re tremendously grateful for our fantastic launch yesterday, ending at #1 for the day. Thank you all for your support!

I started Tonkotsu because I saw a huge opportunity for a complete rethink of AI coding not just incremental adjustments to established tools and workflows. Having managed teams of hundreds of engineers at Meta, Microsoft, and Atlassian, it s been fascinating to me to find that the role of the developer has shifted overnight: you're now the manager of a team of agents. We're building Tonkotsu to help you succeed in that new role.
