What I'm looking for

I am looking for ReactJS/React Native or full-stack roles where I can own features, improve architecture, mentor teams, and deliver cross-platform, maintainable solutions in collaborative Agile environments.

I am a multi-skilled full-stack engineer with fourteen years' experience building business and large consumer applications, working across web, mobile, smart TV and embedded devices for companies such as Sky, Vodafone and Nokia Siemens Networks.

I specialise in ReactJS, React Native and TypeScript, and have delivered end-to-end features, integrations (Xero, QuickBooks, PubNub, Zoom), CI/CD pipelines, and cross-platform debugging on Apple TV, Roku, LG and Samsung devices. I mentor developers, drive architectural improvements, and consistently reduce code complexity while increasing maintainability and performance.

I seek to apply my can-do attitude to ReactJS/React Native or full-stack roles where I can contribute to product architecture, mentor teams, and deliver reliable, user-focused solutions.
