    - To help our client a major international product retailer to deal with demand peaks, I have build a time series machine learning model with scikit-learn to forecast demand, build a neural network to predict peak vs non peaks with python keras. - For a major pharmaceutical company I have developed a data pipeline with R to estimate lead times based on business rules from a lab sheduling system.
