About

I’m a Flutter developer with 4+ years of commercial experience building production mobile and web applications across fintech, e-commerce, and social platforms. Over the past few years, I’ve worked on core features like banking flows (transfers, top-ups, deposits, loans, and loyalty), integrated REST APIs and managed application state, and shipped improvements and fixes that supported real users in production.

I also enjoy taking on end-to-end ownership—during my PhD at Liverpool John Moores University, I independently designed and developed the Smart Green Indoor Air app, including dashboards, data visualisations, personalised push notifications, and the supporting backend in Python/Flask. I’m comfortable working with BLoC/Cubit and clean/modular architectures, and I collaborate with teams to deliver reliable, maintainable Flutter products for app stores and modern platforms.
