Top SchoolMaxim Karvonen is a Lead Software Developer with 14 years of experience designing and delivering robust, maintainable systems across startups and enterprise environments from Yandex to Pitney Bowes and Waratek. He excels at owning the full software lifecycle—requirements, team coordination, architecture, CI/CD and production operations—while prioritizing design choices that minimize mid-to-long-term cost of ownership in dynamic markets. His hands-on background spans backend systems, DI and validation frameworks, workflow engines, real-time notifications, and nuanced serialization fixes in open-source projects like the Redmine Java API.
