I'm a retired mechanical engineer who traded CAD for code. After a career in engineering, I'm now building apps for iOS, Android and the web, and loving every minute of it.
- Currently building: a custom member app and website for a friend's fitness performance center
- Working with: TypeScript, React Native (Expo), Next.js, Supabase, Swift, SwiftUI, Python, JavaScript, HTML and CSS
- Off the keyboard: music, 3D printing and AI
A custom-built replacement for the off-the-shelf booking app at Power Conditioning Inc., a fitness performance center with two locations in Newfoundland. Members get a faster, simpler way to book, and the business gets tools built around how it actually runs.
- iOS and Android app built with Expo / React Native
- Fully integrated Next.js website: the member web app and the public site in one
- Supabase backend, with one shared set of booking rules that the app, the website and the server all use
A privacy-first iOS fitness app that shows your workout patterns and trends over time, using your Apple Health data.
- Built with Swift and SwiftUI
- Download on the App Store · Website
The band website, showing off my (AI-assisted) web development skills and my complete lack of musical talent.
- Built with Eleventy, JavaScript, HTML and CSS
