Rockstar🎓
Top SchoolSascha Timme is a software engineer and co-founder based in Berlin with 11 years of experience spanning mobile, web and research-driven numerical computing. He blends a PhD-level mathematics background with hands-on engineering—leading full-stack product development using React, GraphQL and Postgres while also contributing low-level performance work such as AVX2 optimizations in academic software. As Head of Engineering he built and mentored teams, architected scalable SPAs, and ran the DevOps and hiring efforts for manufacturing-focused SaaS. On the mobile side he has contributed ReScript bindings for React Native iOS components, and has a track record of shipping high-usage consumer math apps and robust backend services. His open-source contributions reflect both UX-focused fixes (progress meters, iJulia support) and language-interop work, showing comfort across front-end, back-end and scientific tooling. Comfortable shifting between product leadership and deep technical implementation, he brings a rare combination of math rigor and production-grade engineering.
