Software Engineer building mobile products and production systems
I build Android applications, backend services, and production systems with a focus on architecture, reliability, and software that remains maintainable as products evolve.
Over the past decade I've worked across media streaming, fintech, banking, travel, and healthcare, building products from idea to production.

About
Engineering with context
I'm a software engineer with extensive professional Android experience in London, working across media streaming, fintech, banking, travel, healthcare, and product development.
My mobile background spans Kotlin and Java, Android TV, Jetpack Compose, Coroutines, MVI and MVVM, dependency injection, networking, persistence, offline synchronization, security, testing, CI/CD, mentoring, and cross-functional technical leadership.
Beyond mobile, I work across backend architecture, Rust, TypeScript, and full-product development. Projects such as the Android Handbook, RelayRadar, and Tonomo are places where those interests meet practical engineering and product work.
