Council Member
Gleb Khmyznikov is a software engineer and recognized expert in Progressive Web Apps, developer tools, and the Python and ML ecosystem on Windows on Arm, with over a decade of experience building developer-facing products and leading cross-organization technical initiatives.
Since October 2022, Gleb Khmyznikov has served as a Software Development Engineer 2 at Microsoft, where he builds tools and services for web application developers through PWABuilder and leads interdisciplinary work spanning developer tooling and the Python ecosystem on Windows on Arm. He founded and hosts Windows Dev Chat, a cross-industry community livestream program connecting Microsoft engineers with external developers; episodes averaged roughly 2,233 organic views each, ranked in the top five on the Windows Developer YouTube channel over a 90-day period, and drove a 25% subscriber increase. His efforts propelled PWABuilder traffic far beyond targets, delivering 170% year-over-year growth on the main site, 196% on documentation, and 80% on the blog, alongside a peak monthly Windows app-packaging growth rate of 10.9%. He authored two flagship technical articles covering PWA in-app purchases on iOS and PWA installation on macOS that together generated 20% of all PWABuilder blog views, while rapidly updating templates and guidance to help developers navigate the EU PWA disruption. Gleb Khmyznikov pioneered Windows on Arm AI and ML enablement by building the ML environment test suite and authoring the "ML ARM DX State" reference that shaped organization-level AI-on-Windows priorities, advancing native non-emulated workloads such as PyTorch. He also originated and led the award-winning FHL AI Subtitles Generator project from idea to working prototype, earning recognition at the PDE All Hands and FHL Showcase and seeding follow-on Windows AI samples. Across this work, he built collaborative networks spanning more than ten Microsoft organizations, including AI Frameworks, SiGMa R&D, ASG, DevDiv, Azure Core, DML, and the Olive and ONNX Runtime teams, as well as external partners Arm and Qualcomm.

Before joining Microsoft, Gleb Khmyznikov served as Lead Web Developer at Hostme from February 2016 to October 2022, where he architected and built the entire client side of a real-time restaurant management platform from scratch. The product enabled the startup to reach self-sufficiency with restaurant clients worldwide. He also pioneered the company's adoption of Progressive Web Apps, delivering a single installable cross-platform application that eliminated the cost and overhead of maintaining separate native builds, and established the deep PWA expertise that later underpinned his open-source contributions and his work at Microsoft. Prior to that, he worked as a Web Developer at Aspirity from December 2014 to January 2016, delivering full-stack web solutions across multiple client projects for a custom software studio. Earlier still, from July 2013 to December 2014, he served as a Web Developer at LangPrism, where he built and shipped the company landing page and reusable integration widgets for a crowdsourced website-translation startup, improving product presentation and customer onboarding.
Outside his primary roles, Gleb Khmyznikov created the open-source PWA Install component, which has accumulated over 2.9 million total downloads, reaches more than 40,000 weekly downloads, and has received contributions from 38 external developers. He also created the Mac and iOS PWA Builder template, which he donated to the Microsoft PWABuilder team. He administers and moderates major PWA developer communities on Telegram and Discord, and has spoken at international conferences and round tables including 404 Fest (2021), a PWA Round Table (2022), and a Doka Round Table (2024).
His published work includes the peer-reviewed research article "Enabling Python Machine Learning Libraries on Windows ARM: Challenges and Solutions," published in the Universal Library of Engineering Technology in December 2024, as well as industry articles in The AI Journal, PlainEnglish, and the PWABuilder blog. He served as a member of the expert council for the National Business Awards Innovation and Tech in September 2023. He is also a winner of the UMNIK innovation grant.
