At Globant, I developed and supported Angular web applications, including Standalone Components embedded in Office Add-ins. I improved performance by 25% and helped reduce post-deployment bugs by 40% through optimization and testing.

As a freelance Software Developer Engineer, I design and build full-stack web applications for independent clients, focusing on responsive experiences, client-side rendering, and clean architecture. I also implement unit testing with Jest and use AI-assisted development for code review and repetitive tasks.
