I'm an Android Engineer who specializes in building high-performance, consumer-facing mobile applications — from Barrie, Ontario (Toronto area), Canada. With 4+ years of professional Android development experience, I've shipped apps used by hundreds of thousands of users across the Google Play Store. My core expertise lies in Kotlin, Jetpack Compose, and modern Android architecture — MVVM, Clean Architecture, and modular design patterns that keep codebases scalable and maintainable as products grow. I'm equally comfortable in the full lifecycle: from architecting new features and integrating complex third-party SDKs, to profiling, debugging, and squeezing out meaningful performance gains (I've cut app launch times by over 50% in production). What sets me apart from other Android developers is a combination of depth and delivery. I don't just write features — I own reliability. I've built CI/CD pipelines that cut deployment time from 4 hours to 45 minutes, written comprehensive test suites that reduced defects by 50%, and worked embedded in cross-functional Agile teams alongside product managers and designers to ship at pace without sacrificing quality. I've also worked across industries including retail/e-commerce (Shopkick), fintech/payments (E-credits), and enterprise SaaS — giving me a broad understanding of what users expect from a polished mobile experience. I hold a Post-Graduate Diploma in Mobile Application Development from Georgian College and actively leverage modern AI-assisted development tools (Claude Code, Copilot, Cursor) to stay ahead of the curve.
