I have spent 10 years building production data science in retail, CPG and pharma. Demand forecasting, price elasticity, promo optimization, shelf-space allocation, AI system design and I currently work as a senior data scientist at a large US retail group. Most of what I get asked about falls into these buckets: how to structure a portfolio project so it reads like real work instead of a Kaggle notebook, how to answer open-ended case rounds for senior/lead roles, and how to move from "person who builds models" to "person who owns a problem area." I have a Master's in Statistics, and I am the kind of mentor who will tell you the uncomfortable version of the feedback. If you want someone to validate your existing plan, I'm probably the wrong booking. Come with a specific problem - a JD you are targeting, a resume, a project you're stuck on and we'll get further in 30 minutes.
