Summary
👤
Senior🎓
Top SchoolJustin Topham is an experienced iOS and video game developer with nearly two decades of software lifecycle experience and a strong track record of shipping solo projects through his company, Just Mobile Games Ltd. He blends hands-on development in Swift, Objective‑C, C#, C++ and Unity with deep technical authoring—creating developer academies, API docs and working code examples for projects like the Stratis Bitcoin full node and bespoke SpatialOS integrations. Equally comfortable writing low‑level examples in Arm assembly or producing consumer‑facing iOS apps, he has a knack for translating complex systems into clear, usable documentation and tooling. Justin’s consultancy roles show an ability to rebrand documentation strategies and migrate content platforms, while his game work includes award‑winning Pocket PC titles now being ported to Unity. Based in Cambridge, he pairs commercial awareness with curiosity-driven technical problem solving, often inventing new approaches when existing methodologies fall short.
