Hands-on support
I am an AI and machine learning scientist and tech founder with a PhD in Astrophysics. I spent many years in academia before moving into industry, where I worked as a machine learning scientist at Amazon and IBM. In recent years, I have focused on large language models (LLMs), retrieval-augmented generation (RAG), agentic workflows, and a broad range of other machine learning methods. I specialize in turning research thinking into production-ready systems, reliable evaluation loops, and reusable technical solutions. Book an intro call or a one-off session to get started!
