What I'm looking for

I seek senior Android roles where I can modernize apps, improve performance and reliability, mentor teams, and drive engineering best practices in Agile environments.

I am a Senior Android Engineer with 8+ years building scalable, reliable Android applications across fintech, IoT, and enterprise domains, with deep expertise in Kotlin, Jetpack, MVVM/Clean Architecture, modularisation and performance optimisation. I have modernized high-download apps, led Android migrations, reduced CI/CD times and crash rates, and introduced best practices and mentoring across teams.

My work includes migrating large apps to modern architectures, integrating Jetpack Compose and deep linking to boost engagement, and delivering security and compliance updates. I consistently focus on improving developer productivity, accessibility, and reliability while driving measurable user and engineering outcomes.
