• Experience implementing interfaces from detailed visual specifications and using design systems such as IBM Carbon or Material UI.
• Strong REST API integration experience, including typed models, adapters, polling and defensive handling of missing or inconsistent data.
• Experience defining or validating API contracts with backend teams and applying contract-testing principles.
• Demonstrated performance expertise, including profiling, memoisation, code splitting, lazy loading and bundle analysis.
• Awareness of frame rate, GPU utilisation and memory behaviour on graphics-heavy screens.
• Hands‑on experience with WebGL, three.js or React Three Fiber, including scene and camera control, pointer picking and animation timelines.
• Experience managing events and interaction across layered UI and graphics surfaces.
• Experience integrating map SDKs, handling coordinate systems, implementing provider fallbacks and managing API tokens safely.
• Ability to build components that integrate into an existing host application through clean props and callbacks, isolated styles and no unintended global side effects.
• Strong testing experience with Vitest or Jest and React Testing Library, supported by a practical test strategy.
