Top SchoolCezary Stefanski is a Senior Software Development Engineer based in Warsaw with 11 years of experience building and leading front-end teams and initiatives. He combines hands-on React and modern JavaScript engineering with a track record of driving cross-team improvements, architectural visions (including microfrontends and clean architecture), and developer onboarding across multiple markets.
