Scouting report

Algorithms/simulation specialist with CS depth

assessed from open-source footprint

Senior

66signal

Sebastian is a computer-science-heavy builder strong in algorithms and simulation — a Simulated Annealing solver for the number-partitioning problem (1★) and a discrete-event population simulator in Julia — with high consistency (93) and a Data/ML lean. Honest flags: near-zero stars and no deployments mean this is academic-grade rather than product work. A good fit for a junior backend/data role valuing algorithmic and modeling rigor.
