Rapperswil-Jona, St. Gallen, Switzerland
Summary
🤩
Rockstar🎓
Top SchoolChristoph Rüegg is a software architect with 20+ years of experience who blends systems-level numeric computing with distributed-algorithm design, from cloud services down to custom ASIC and VHDL implementations. He has been a principal maintainer of the Math.NET open-source ecosystem for two decades, contributing deep linear-algebra improvements such as optimized matrix multiplication, SVD-based pseudo-inverses and point-wise operations. At Sonova he drives architectural decisions while his past roles include founding an engineering consultancy and research-driven development at Lokad and Microsoft. Comfortable in Rust, F#, C# and hardware description languages, he also improves developer experience through build and dependency tooling work (notably Paket). Based in Rapperswil-Jona, Switzerland, he pairs academic roots from ETH Zürich with a pragmatic, performance-first approach to numerical and distributed systems.
