Nikita Vorobev is a software engineer with 10 years of experience focused on backend development, low-level systems work, and applied machine learning. Educated in Applied Mathematics and Informatics at ITMO University, he has rewritten a Linux kernel module for a Mellanox 100G NIC and balances hands-on development with business-analysis responsibilities in his current role. He contributes to open-source education software like Oppia, improving both frontend and backend behavior to enhance learning experiences. A longtime Haskell enthusiast who studied type theory deeply, he pairs mathematical rigor with practical engineering—having also implemented GANs and trained transformers. He has led teams for 18 months and enjoys teaching, which has sharpened his communication and helped him internalize core CS concepts. Fast-learning and intensely curious, he continually pursues new courses and self-study across CS, math, and ML.
