  • Translating complex, real-world business problems into mathematical models using variables, constraints, and objective functions.
  • Utilising optimisation solvers (e.g., Gurobi, CPLEX, OR-Tools) to solve NP-hard problems involving discrete choices and constraints.
  • Building scalable, production-ready pipelines and integrating models into live client-facing systems.
  • Developing linear, non-linear, stochastic, and heuristic-based models.
  • Working with product squads, engineers, and stakeholders to define business goals and translate them into actionable, data-driven decisions.
  • Monitoring models for speed, robustness, and precision, troubleshooting slow convergence, and iterating on algorithms.
  • Produce project plans, designs and prototype solutions to demonstrate early benefit and value.
