Vlad Fatenko is a Senior Software Engineer with 11 years of experience combining strong mathematical training and production-grade C++/Python engineering, now building systems at Google. He has a background in quantitative development for trading and statistical computing, contributing bug fixes and efficiency improvements to the high-profile Stan probabilistic programming project. Comfortable moving between core algorithmic work and pragmatic optimizations, Vlad focuses on correctness and performance in numerical code, drawing on a Master’s in Mathematics and Computer Science from Kyiv Polytechnic Institute. Based in Poland, he brings a researcher’s attention to probability and statistical analysis to large-scale software problems, with a track record of improving core library components rather than surface features.
