At recent roles I led creation of component libraries and a TypeScript framework that accelerated delivery by up to 60%, implemented micro-frontend architectures to modernize legacy platforms, and mentored multicultural teams to raise engineering quality through clean code, rigorous reviews, and CI/CD practices.
