8+ years experience designing and implementing optimization models, with an emphasis on vehicle routing, scheduling, and inventory planning. Expertise in python, using Google OR-Tools (open-source), GLPK (open-source), CPLEX or Gurobi for solving models. I have also built models in Excel using Excel Solver and Analytics Solver. Significant experience reading/writing to/from ODBC data sources and cleaning / prepping data for optimization, as is generally required.
I also have experience interacting with APIs via python, including Google Maps, Google AI, and GraphHopper.
