Summary
👤
Senior🎓
Top SchoolJohan Von Tangen Sivertsen is a quantitative software developer with 11 years of experience combining research-grade randomized algorithms with production engineering. He holds a PhD in Computer Science focused on high-dimensional similarity and locality-sensitive hashing, and has translated that theory into robust numerical methods for pension probability engines and precision-critical systems. Johan has taught algorithms and databases at university level and has a track record of implementing careful numerical integration and correctness-driven code in Financial Services. Comfortable across C# and research codebases, he brings rigorous mathematical thinking to practical product problems and has repeatedly turned academic ideas (e.g., kernel approximation and LSH) into deployable solutions. Based in Copenhagen, he pairs deep theoretical expertise with a pragmatic bent—often optimizing for numerical stability and repeatability where others optimize for speed alone.
