About

Building mobile apps that matter

I'm a Mobile Technical Lead with over 8 years of experience building and shipping production apps on Android, iOS, and Flutter. I've worked across fintech, telecoms, and gaming — leading teams, shaping architecture, and caring deeply about user experience.

From Luno's crypto trading app to Rain's telco platform, I've owned complex mobile journeys end-to-end — from architectural decisions and CI/CD pipelines to mentoring engineers and obsessing over crash rates.

When I'm not in a codebase, I'm usually behind a camera — finding the quiet details that make ordinary scenes extraordinary.
