Summary
🤩
Rockstar🎓
Top SchoolHamilton Chapman is an experienced engineer based in London with 12 years building developer-facing products and SDKs for web and mobile platforms. He helped take Pusher’s Chatkit from concept to revenue by building multiple SDKs (Swift, JS, Ruby, Node, PHP) and contributing to server-side Go services deployed on Kubernetes, and he previously modernised Channels and Feeds platform components. Hamilton is comfortable across the stack—authoring robust back-end logic, improving mobile libraries (Objective-C/Swift), and refactoring code for maintainability and data integrity, as shown by his contributions to popular open-source Pusher clients. At Ditto he continues applying that product-focused engineering mindset to shipping reliable systems. A first-class Mathematics graduate from the University of York, he combines strong analytical grounding with practical experience in developer tooling and distributed services. Colleagues value his blend of hands-on implementation, platform thinking, and an eye for simplifying examples and dependencies to make SDKs easier to adopt.
