What I'm looking for

I'm looking to build and improve production web products where I can own front-end architecture, contribute product and UX judgment, modernize platforms, and apply AI-augmented development workflows with cross-functional teams.

I've built public-facing financial calculators at ATB, including a reusable React and Next.js component library shared across 12 applications. I also established the team's first AI-assisted development workflow using Google Gemini.

At WestJet, I led Vue 2-to-Vue 3 migration work for homepage search, rebuilt API integrations, and helped unify booking experiences during the Swoop merger. My work spans performance, reliability, shared components, and cross-functional product delivery.

I'm also building Bounty, a Canadian grocery price-scanning app, and ForModele, a portfolio platform for models and creatives. Across 30+ years, I've combined front-end engineering, UX, product judgment, and AI-augmented workflows to take products from concept through production.
