Summary
🤩
Rockstar🎓
Top SchoolMathieu Dutour Sikiric is a PhD-trained mathematician turned software researcher and developer with 20+ years applying computation to mathematics, oceanography, chemistry and embedded systems, now based in Zagreb. He specializes in high-performance C++, Rust, Fortran and Python code, with deep experience in parallel and distributed programming (MPI, OpenMP, POSIX/C++11/Qt threads) and production-grade database backends. Mathieu has a strong record of shipping reliable, optimized software from prototype to operation, evidenced by contributions to notable projects such as WAVEWATCH III and the Linera protocol where he re-architected storage layers for significant performance gains. He combines academic rigor—4 books, 86 articles, and conference talks—with practical debugging craftsmanship and an obsession for code quality. Comfortable moving between numerical modeling, combinatorics, geometry and optimization, he excels at translating hard mathematical problems into realistic, performant solutions.
