Rockstar🎓
Top SchoolDavid Cummings is a seasoned engineering manager and hands-on software developer with 11+ years building developer tools and IDEs, now leading Development Technologies at Apple with a focus on build systems, package management, performance tools, IDEs and Swift. He combines technical leadership with hands-on problem solving—implementing features, fixing hard bugs, designing CI/CD, and improving developer workflows across large organizations. His background spans QNX (Momentics IDE, SDK delivery, React/Vert.x prototypes) to IBM and multiple roles at Apple, giving him deep expertise in tooling, cross-team coordination, and shipping platform improvements. An avid tinkerer, he builds hardware-software projects in his spare time (e.g., a Raspberry Pi quiz-game that won a maker contest) which reflects a practical, product-focused curiosity. Colleagues rely on him to bridge product, engineering and customer needs while mentoring teams to deliver reliable developer experiences at scale.
