I'm a Full Stack Data Scientist who has worked with LLMs since GPT-3 Davinci — building AI agents and chatbots before they were mainstream. Through consulting and commercial experience across ML and DS domains, I now specialise in performance marketing, forecasting, and optimisation. I built these tools to make quantitative marketing methods accessible to teams that don't have a dedicated data scientist. Your data is processed server-side and never stored or shared.
