Top SchoolSeweryn Kalemba is a React-focused software engineer and serial co-founder based in Krakow with eight years of hands-on experience building web products and teams. He has progressed from web developer roles into founding startups (Gotowi, Splot) while maintaining a strong front-end practice honed during a multi-year tenure at Codeshine and a brief engineering role at Atende. Comfortable bridging design and code, he also brings visual storytelling skills from years as a video editor and graphic designer, which inform his UI sensibilities. Seweryn combines formal computer science training with practical startup experience, favoring pragmatic, user-centered React solutions that ship quickly.
