ColombiaWhat I'm looking for
Mathematical Engineer (EAFIT) working in Operations Research — mixed-integer programming, heuristics, and decision models for problems where exact methods stop scaling. Most recently a bi-level MIQP solver for cardinality-constrained portfolio optimization. Also two years in data engineering, because optimization models fail more often from broken data than bad formulations. Python, Gurobi, Pyomo.
