About

I’m a Senior Mobile Engineer with 11+ years of experience, specialising in React Native and native iOS development. My work focuses on building stable, scalable mobile applications with clean architecture, strong performance, and predictable delivery. I enjoy working on end-to-end features, improving code quality, and strengthening team practices through mentoring and clear technical direction. Most of my recent work has been in financial and digital product environments, where reliability, security, and structured engineering approaches really matter. I’ve contributed across architecture, feature development, CI/CD, testing, performance optimisation. I’m comfortable collaborating with cross-functional teams, backend, QA, design, DevOps, and product, to ship features that are both technically sound and aligned with real user needs. I value clarity, maintainability, and building mobile systems that scale well over time. Outside of mobile engineering, I enjoy learning backend concepts, improving my system design skills, and working on small creative projects, including content around my pet budgies.
