Dima Fedoriaka

Dima Fedoriaka is a Senior Quantum Software Engineer at Microsoft in the Seattle area, working on quantum computing - quantum arithmetic circuits, resource estimation and quantum software (Q#/QDK). Before Microsoft he was a Senior Software Engineer at Google and at Databricks. Ukrainian by origin, he represented Ukraine at the IOI 2013 and won a bronze medal, and he is an active competitive programmer on Codeforces (handle 'fedimser', Master, rating ~2149). He holds a bachelor's in Applied Mathematics and Physics from MIPT and writes research papers on quantum circuits and, with the CayleyPy project, AI for group theory.

• Represented Ukraine at IOI 2013 (Sydney), earning a bronze medal with 253 points, ranked 133rd of 299 - the same score as Canada's Yuanhao Wei. Handle on Codeforces is 'fedimser'.
• Represented Ukraine at IOI 2013 (Brisbane/Sydney), earning a bronze medal with 253 points, ranked 133rd of 299 - the same score as Canada's Yuanhao Wei. His Codeforces handle is 'fedimser'.
• Career trajectory Google (2016-2021) -> Databricks (2022-2025) -> Microsoft (2026-) shows a steady move from big-tech SWE toward specialised quantum software; his published work shifted to quantum arithmetic circuits around 2024-2025.
• Personal site fedimser.github.io describes him as 'Dima Fedoriaka' and links his GitHub, LinkedIn and Codeforces - confirming all handles belong to one person.
• Personal site fedimser.github.io identifies 'Dima Fedoriaka' and links his GitHub, LinkedIn (in/fedimser) and Codeforces - confirming all handles belong to one person.
• 'CayleyPy Growth' (2025) with Alexander Chervov and Elena Konstantinova applies AI to group theory and produced ~200 new conjectures; presented at the 5th Workshop on Mathematical Reasoning and AI at NeurIPS 2025 - he pairs quantum engineering with pure-math research.
• 'Quantum Arithmetic Algorithms' (IEEE QCE 2025, with Yingrong Chen and Brian Goldsmith) came out of the QOSF Quantum Computing Mentorship Program; presented 2025-09-04 - indicates he mentors/participates in the quantum mentoring community.
• Authored 11 publications on ResearchGate / Google Scholar under 'Dmytro Fedoriaka', cited 8 times - an active research output on top of his engineering role.
• Received a bachelor's in Applied Mathematics and Physics from MIPT and began a Master's in Computer Science at the University of Washington - moving from Ukrainian/Russian STEM training into the US quantum ecosystem.
• Instagram @fedimser7 bio reads 'SWE@Microsoft, Seattle' - matches his employer and location, corroborating the account.
