What I'm looking for

I seek a collaborative, product-focused engineering role building scalable Android apps, modernizing mobile stacks, and mentoring teams while delivering measurable user and performance improvements.

I am an experienced Android developer with a Computer Engineering degree from York University and a decade-plus track record building and modernizing mobile apps for major Canadian enterprises. I have led feature development, large refactors and SDK integrations across banking, telecom and insurance apps, improving performance, reliability and user-facing capabilities.

I focus on maintainable architectures (MVVM, repositories, use cases), Kotlin migrations, Jetpack Compose, analytics and feature-flag frameworks, and production support. I collaborate closely with product, QA and engineering teams to reduce technical debt, add automated tests and deliver customer-facing features at scale.
