About Sihao
I’m an Operations Research / Optimization Engineer (M.Sc. student at TU Dresden) specializing in routing & scheduling (VRP/VRPTW), MIP/CP and simulation-based optimization for logistics, ports and manufacturing. I build clean, reproducible Python solutions: data prep (SQL/Oracle), model formulation, solver selection & tuning (OR-Tools, CPLEX/DOcplex, Gurobi, COPT, GAMS), and clear KPI reporting. Typical deliverables include a validated optimization model, well-documented codebase, experiment scripts, and a short report (LaTeX/Markdown). I’m comfortable working with ambiguous real-world constraints, iterating fast, and handing over production-ready artifacts (optional API integration).
