Rockstar🎓
Top SchoolSebastian Waisbrot is a versatile software engineer and teaching assistant with 16 years of experience building production systems across startups and large organizations, from Twitter and Despegar to fintechs like Brubank and MURAL. He combines backend, DevOps and full-stack skills—shipping features, improving test suites, and automating infrastructure—while contributing to notable open-source Rust projects such as Amethyst and ncollide. His work spans practical problems like fraud detection, ID/liveness services and cache backends, plus research-adjacent roles in digital justice and public-sector data systems at ANSES. Currently engaged in teaching at the University of Buenos Aires and active in the Observatorio de Derecho Informático Argentino, he brings a rare mix of technical craft and legal/economic studies (Law and Economics). Equally comfortable fixing low-level rendering and configuration bugs or designing integration tests and CI automation, he has a proven eye for robustness and edge cases. Based in Vicente López, he pairs hands-on engineering with multidisciplinary curiosity in technology’s societal impacts.
