Skills: Divider

Through my extensive experience I've gained a vast array of skillsets and expertise in a range of web and native technologies. I have a keen focus on thoroughly tested, scalable and maintainable code - which is performant and accessible - and live by the mantra: write less, do more! Next, Node, React Native and TypeScript is my preferred tech stack but I’m a firm believer in using the right tool for the job.

As a T-shaped engineer, I value collaboration with members of the wider project team across different disciplines. Having experience of leading teams and mentoring other engineers, I also find the management side of the job really rewarding, while at the same time cherishing the technical challenge of being an expert engineer. I am passionate about usability and accessibility and how these enhance UX.
