Summary
🤩
Rockstar🎓
Top SchoolSergei Rybakov is a Founding Principal Engineer based in Munich with 11 years of experience building data platforms and backend systems for computational biology. He helped found and evolve lamin.ai's data layer, previously shaping its core platform as a Founding Software Engineer, and has bridged research and engineering through roles at Helmholtz Munich. A core developer on scverse/scanpy and contributor to the widely used anndata library, he implemented advanced data access patterns (chunking, batching, layers and sparse handling) that materially improved large-scale single-cell workflows. Sergei combines rigorous mathematical training (MSc in Mathematics in Data Science, TUM) with hands-on production engineering, making him as comfortable optimizing algorithms as shipping robust backend services. Colleagues value his ability to translate research-grade code into scalable, developer-friendly tooling.
