Alex has led large migrations (jQuery/Backbone → Vue + TypeScript), designed front-end microservices to enable continuous delivery, and owned SDKs and complex release flows. Comfortable coaching teams and shipping pragmatic solutions, he pairs hands-on coding with mentorship and process improvements. An under-the-radar strength is his history of reducing memory leaks and improving legacy component architecture, which keeps long-lived web apps performant and maintainable.
