I build production mobile and web software, mostly where Android architecture, Kotlin Multiplatform, product polish, and developer tooling overlap.

Lead Android Engineer at Disney+. I use AI-driven development heavily in my day-to-day loop, but the bar is still the boring stuff that survives contact with production: clean diffs, useful tests, readable architecture, and releases that do not turn into archaeology.

Open to contract work and worthwhile engineering conversations through LinkedIn.

	Liftoff iOS / Android · App Store + Google Play Rocket launch tracking with a countdown-first feed, mission detail, launch alerts, supported SpaceX telemetry, and Android widgets.
	KTK Creative Web · photography / videography business Custom production site for my wife's photography business: portfolio, services, inquiry flow, and admin-managed content.

Squares · Web / PWA · Live demo · Repo
Full-stack realtime multiplayer web app. SvelteKit 5, Supabase Realtime, Cloudflare Pages, CI, ADRs, and a production run with real users.

PomoDaddy · macOS · Releases · Homebrew cask
Menu-bar Pomodoro timer built with SwiftUI and SwiftData. Local-first, Homebrew-installable, and named exactly as seriously as it needs to be.

kmp-template · Kotlin Multiplatform · Template repo
Production-oriented iOS/Android starter with Compose Multiplatform, code quality gates, and AI-assisted project generation.

app-icon-banner · Gradle / KMP · Gradle Plugin Portal · Repo
Gradle plugin that stamps Android and iOS app icons from one DSL. Small tool, real developer-experience problem.

• Android / KMP - Lead Android at Disney+; building mobile systems where product UX and architecture both matter.
• Realtime web - Squares is the public example: SvelteKit, Supabase Realtime, PWA, production runbook.
• Developer tooling - KMP templates, Gradle plugins, release-loop cleanup, and anything that removes repeat work.
• AI-driven development - Heavy daily use for implementation, review, automation, and verification. The output still has to be maintainable code.
