About

I have spent 10+ years shipping web applications, with a core focus on React and Vue 3. That includes migrating enterprise apps from AngularJS to React for 10,000+ users while keeping WCAG compliance in the picture. I also build backends in Go and C# .NET when the job needs more than a polished UI.
