What I'm looking for

I seek roles applying optimization and simulation to operational problems, in data-driven teams where I can implement models, validate solutions, and support strategic decisions.

I am a Computer Science student focused on Operations Research and Mathematical Optimization, with hands-on experience applying models to real-world operational problems.

In laboratory and research settings I have led data collection, SQL extraction, and Python-based data processing to feed optimization and simulation models.

I developed optimization solutions using PuLP/OR-Tools/Pyomo, implemented discrete event simulation frameworks, and validated models with historical and simulated scenarios, estimating a ~20% reagent cost reduction on a freelance project.

I value data-driven, robust solutions that improve predictability and support managerial decision-making, combining analytical rigor with practical implementation skills.
