Summary
🤩
Rockstar🎓
Top SchoolJan-david S is an applied science and engineering manager based in Berlin with 7 years of professional experience bridging research-grade algorithms and production systems. He currently leads development of batching algorithms at Zalando, turning NP-hard order-batching theory into microservices (Scala/Kotlin) and MILP solutions that reduce warehouse worker travel. Previously he progressed from senior Scala engineer to team lead at Mendix, pairing hands-on coding with coaching and cross-team technical leadership for a low-code runtime. His background includes a rigorous academic foundation in mathematics and symplectic topology, which informs a principled approach to heuristic design and optimization. Known for owning end-to-end delivery—from mathematical models to deployed services—he thrives on making complex algorithmic ideas operational at scale. As a detail that sets him apart, he combines pure-math research experience with practical enterprise engineering, enabling uncommon depth when solving combinatorial production problems.
