Summary
👤
Senior🎓
Top SchoolMarek Kaluba is a freelance software engineer and former academic with a PhD in algebraic topology and over a decade of experience translating deep math into high-performance research software. His work spans topological data analysis, non-commutative optimization, and certifying approximate solutions, and has appeared in leading journals including the Annals of Mathematics. He built influential Julia packages (SymbolicWedderburn.jl, StarAlgebras.jl) that integrate with JuMP and has contributed build and release automation for widely used BinaryBuilder/Yggdrasil infrastructure, including multi-platform SCS solver builds. Marek combines rigorous formal thinking from geometric group theory and functional analysis with practical engineering: simplifying optimization problems and producing reproducible, production-ready tooling. He was awarded the Frontiers of Science prize at the International Congress of Basic Sciences in 2023, reflecting impact across theory and software. Based in Zurich, he now focuses on freelance projects that bridge mathematical research and scalable optimization systems.
