Top SchoolChris Witalewski is a Senior Software Engineer with 15+ years of front-end and mobile experience, currently shaping AI-driven, consumer-facing features at Cleo using TypeScript, React and React Native. He combines product-focused engineering with cross-functional leadership—having acted as Scrum Master and tech lead—to influence frontend patterns and drive consistent quality across teams. His background spans startups and YC-backed companies where he shipped greenfield projects like real-time collaboration tools and AI note-taking for EHRs, and he’s comfortable touching backend services (Python/FastAPI) when needed. Motivated by work that benefits health, community and the environment, he brings deep domain experience in healthcare, pharma and public transport as well as four years in NGO leadership. Notably, he began his career on Adobe Flex/ActionScript and has continually evolved his stack while remaining open to new frameworks like Flutter and Next.
