- Develop statistical model using Monte Carlo simulations to analyze probabilistic distributions for customer's innovation and development portfolios using python Pandas and Numpy- Help to put on workshops and retrospectives with various SmartOrg customers that help them to develop innovation strategies through the used of probabilistic decision tree models and decision analysis.- Wrote Restful API for doing automated reading of customer portfolio investment models create in excel into JSON files for configuring SmartOrg Portfolio Management tool. Restful API was written in python using Flask for the Restful API and Pandas and Openpyxl python libraries for reading in and extracting the data and calculations from the Excel template model
