Profile

I’ve been programming since I was ten, and I’ve worked with neural networks since 2015 (seven years before ChatGPT). For example, in my master’s thesis, I trained a recurrent neural network that significantly improved on the state of the art in real-time event detection in brain signals. These days I mostly direct AI agents, both for coding and for research. I’ve lived every step change in LLM agent capability up close. I enjoy learning new things and do so quickly: from the physics and technology of how something works, to its implementation, the people involved, and the business case. I like to think I’m a clear and convincing communicator, with an eye for visual design and the bigger picture. I like taking the lead: setting a vision, explaining it clearly, and getting people behind it.
