More About Me
Outside of work, I’m fascinated by shipwrecks and coastal archaeology at risk from erosion. I also love math and logic puzzles, and spend weekends solving problems just for fun. When I’m not at a desk, you’ll usually find me at the gym 4–5 times a week or catching waves in Devon.
Unlike many programmers who started coding in childhood, I took the long way around before discovering this passion. That journey has given me a broader perspective, and I bring that mix of experiences into everything I do.
Before moving to the UK, I spent nearly eight years in Shanghai working across roles from exhibition curator to online marketing manager and product manager. Eventually, I realized I wanted something different. A role centered on research, tangible skills, and working with objects, without the constant networking and dress codes. I didn’t initially plan to become a developer or software engineer, but sometimes life leads you in new directions when you keep working hard and learning with purpose.
