Hi, I’m Aliaksandr Mandryk, a mathematician turned software engineer with a passion for solving complex optimization problems and building robust retrieval systems. I’ve published research in hyperbolic PDEs and have hands-on experience from Google, Yandex, InstaLOD, Numeca, and Ciklum, working across algorithms, computational geometry, and large-scale data analysis. I enjoy turning theoretical insights into practical software, collaborating with teams, and continually learning new tools. In my spare time I participate in programming contests and love geometry.…Hi, I’m Aliaksandr Mandryk, a mathematician turned software engineer with a passion for solving complex optimization problems and building robust retrieval systems.
