PSR is a world-renowned provider of analytical tools and consulting services in the areas of electricity and natural gas, acting in more than 70 countries on all continents. I worked in the software development and modeling teams with the role of developing and extending the SDDP model, our program for calculating the hydrothermal dispatch operation, to maintain its status as the state-of-the-art software in this field. I have also been involved with research and modeling projects regarding stochastic optimization and energy dispatch in the presence of renewable energy sources.My everyday tasks include:• Development of distributed algorithms that run in environments with thousands of cores.• Programming and maintenance of polyglot codebases with modules written in languages ranging from Fortran and C++ to Julia, Python, and Lua.• Versioning and Continuous Integration via GitHub, with automated test suits and continuous deployment directly to AWS.• Research state-of-the-art methods to guarantee the programs we write are always correct and the most efficient in the business.

In this technical collaboration between the Federal University of Rio de Janeiro (UFRJ) and the Brazilian Independent System Operator (ONS), I was involved in modelling the Brazilian interconnected power system through the use of disjunctive constraints and researched the beneficial effects that taking long-term decisions under uncertainty can have on the convergence and solvability of this kind of problem. This second topic formed a major part of the inspiration for my Master's thesis (called Convexification by Averages) and also supplied a ground for testing its real world applicability.

During my degree, I was involved in research projects concerning applications of computational geometry for data classification via pairwise rankings and simulations of physical phenomena, such as self-deforming bodies.
