I'm a Senior Mobile Engineer with 8 years of experience building production mobile applications across Android, iOS, React Native, and Flutter. I've worked across the full arc of mobile engineering: 0-to-1 product launches, legacy app rebuilds, hands-on development, and leading teams through architecture migrations. Architecture is what I care about most. My goal in every project is to build systems that are clean, testable, and maintainable, so the team behind them can keep moving fast without accumulating debt. That thinking has shaped every role I've had, whether I was writing the code or reviewing someone else's pull request. My stack: React Native · TypeScript · Flutter · Swift / SwiftUI · Android (Kotlin/Java) · Clean Architecture · MVVM The chapter of my career that surprises people most is the 3 years I spent as a Mobile Developer Advocate. It made me a significantly better engineer where I had to truly understand our architecture in order to explain it clearly, write docs that cut developer onboarding time by 30%, and build trust with external developers. That ability to communicate complex systems clearly is something I bring into every team I work with. A few things I've shipped that I'm proud of: — A full iOS rebuild of a field operations app, including a custom offline sync engine for workers in low-connectivity environments — Offline-first B2B Android products with hardware SDK integrations (thermal printers, real-time socket communication) — A cross-platform architecture migration at scale, improving testability and delivery speed across a multi-product React Native codebase Currently leading mobile engineering at RightCom. Open to senior and lead remote contract roles globally, especially teams where architecture and code quality matter.

Senior Mobile Developer at WorkerNav
April 1, 2025 - November 30, 2025
Full iOS rebuild of a field-operations application used by workers across multiple sites. Rebuilt the iOS app (v3) entirely in SwiftUI with Clean Architecture — decoupling business logic from UI to enable rapid feature delivery. Designed and built an offline-first sync engine with conflict resolution for field workers operating in low-connectivity environments. Integrated AI-powered reporting modules used daily by field workers across multiple construction and service sites. Defined shared API contracts with backend and Flutter engineers to ensure consistent cross-platform behaviour and eliminate divergence from the previous version.

Lead cross-platform architecture migration to Clean Architecture across React Native codebases, improving testability and delivery speed. Manage and mentor a team of mobile engineers; own the mobile technical roadmap and coordinate API contracts with backend teams. Introduced PR review workflows and documentation standards that reduced integration bugs and shortened engineer onboarding time.
Mobile Application Developer at RightCom
March 1, 2018 - December 31, 2021
Built offline campaign broadcast mode for a digital signage product — assets downloaded, decompressed, and locally cached so screens run without internet connectivity. Implemented thermal printer SDK integration (Star, Epson) in enterprise Android kiosks, managing full print lifecycle including error handling. Integrated Socket.io for real-time queue state updates and remote device management across multiple B2B products. Contributed to Bitbucket Pipelines CI/CD setup for automated build, signing, and APK delivery.
