Top SchoolMaciej Ziehlke is a seasoned full-stack JavaScript engineer with over a decade of commercial experience and 15 years in web development, now working at LSEG after senior roles at Tesco, Wayfair and Johnson & Johnson. He blends hands-on Node/TypeScript backend work with React-based frontends, having delivered mission-critical projects from Open Banking directories to retail till software and last-mile delivery tracking. As founder of DigitalMIO he pairs agency-style creativity with product-focused execution, comfortable across microservices, GraphQL, AWS and CI tooling. Colleagues rely on him to translate demanding, time-sensitive requirements into reliable, test-covered systems.

An understated strength is his track record of shipping production systems that support business-critical decisions for large brands.
