Mobile Engineering · Android · iOS · Flutter

I'm a mobile developer with experience across native Android, native iOS, and Flutter applications. My professional work includes healthcare, commerce, and field-team workflows.

I'm interested in the engineering decisions behind dependable mobile products: clear architecture, maintainable code, and a thoughtful user experience.

An original Flutter showcase of resilient mobile architecture: predictable state, clear service boundaries, and useful content even when requests fail.

• Resilient reads: cache-first loading, safe refresh, shared requests, and tested freshness across TTL boundaries and clock rollback.
• Request-race demo: watch a newer search win when an older request finishes or fails later; reset safely during a request.
• Accessibility improvements: keyboard navigation, visible focus, accessible control/status labels, and layouts tested at 320 logical pixels with 2× text.
• Optional HTTP adapter: typed failures, an 8-second deadline, strict JSON validation, and session-owned cancellation that protects shared callers.

64 passing automated tests, with green CI for formatting, analysis, tests, and the release web build. Real HTTP smoke checks also passed on the Dart VM and a browser; native Android/iOS transport testing remains a separate follow-up.

The public demo uses fictional products and a simulated service—no installation, sign-in, API keys, or catalog backend required. HTTP is an opt-in adapter with local fixtures. Architecture decisions and a contribution guide explain the tradeoffs and how to extend the lab.

An original Kotlin and Jetpack Compose checklist demonstrating durable offline storage, lifecycle-aware state, atomic updates, and recovery from save failures. Includes unit and Android device tests.

The native app runs on Android 8.0+. The browser companion lets visitors try packing, filters, saved selections, and save-failure recovery without installation or sign-in. It uses separate local browser storage and fictional sample data.

An original offline field journal exploring native iOS architecture: SwiftUI navigation, searchable notes, favorites, actor-backed persistence, and Swift Testing. Includes an Xcode project and four core behavior tests.

Quick walkthrough: open the project in Xcode, search the sample notes, favorite an entry, create a note, and relaunch to see local persistence. See the repository for exact Xcode and simulator requirements. This is a native iOS demo; it does not run in a browser.

An original web demo with room availability, reservations, cancellation, and database-enforced double-booking prevention. Try two competing requests for one slot in your own anonymous sandbox.

Includes 13 automated tests, a server-rendered interface, and a contribution guide. All rooms are fictional; demo reservations reset on server restarts.

An original .NET 10 showcase with a browser dashboard for queued orders, bounded background processing, retry recovery, and idempotent submissions.

Includes 18 automated tests and GitHub Actions checks, including deterministic retry timing and cancellation during backoff. Run it locally to watch successful delivery, temporary failures that recover, and exhausted retries. Repeating a request demonstrates duplicate-job prevention. Fulfillment is simulated, orders are held in memory, and no public deployment is available.
