What I'm looking for

I'm looking to build high-impact web products and platform capabilities, working across frontend and backend systems with modern cloud infrastructure, strong testing practices, and measurable customer outcomes.

At COGECO, I'm leading an SEO-focused migration from React to Next.js, improving search rankings by 35% and reducing page load times by 40% through server-side rendering and performance tuning.

I've built accessible, responsive and internationalized web experiences, as well as CMS-driven features with Sanity, GraphQL and third-party APIs that allow non-technical teams to update content without deployments.

Previously at Newforma, I launched an Outlook add-in using C#/.NET and React/TypeScript that improved customer conversion by 25%. I also designed services for high-volume email workloads and CI/CD pipelines that delivered 50% faster builds.

At Stay22 and Scotiabank, I built Python automation that reduced manual labor costs by 90%, reusable React patterns adopted across five product areas, and internal payment-monitoring applications. I work across React, TypeScript, .NET, Python, cloud infrastructure, databases and automated testing.
