Rockstar🎓
Top SchoolGleb Mazovetskiy is an experienced software engineer with 15 years of hands-on practice across startups and large organizations, now based in London. He blends deep systems and backend expertise (C/C++, embedded, performance tuning) with strong Ruby/Rails and front-end contributions, having improved projects ranging from Bootstrap to the Bullet Physics SDK and Buildroot. Before joining Google he spent six years as a startup tech lead, wearing non-technical hats from marketing to accounting, which informs his product-minded engineering approach. An active open-source contributor, his work includes notable fixes and refactors—packaging gems, optimizing collision detection, and hardening emulator and build systems—that surface in widely used projects. He studied mathematics early on and holds international business training, a combination that fuels both rigorous problem solving and practical commercialization instincts. Colleagues can expect an engineer who iterates quickly, values modular, testable code, and enjoys "open-source all the things" in practice.
