// Technology Lead · Toronto, Canada

Carlos Dutra

I lead development of high-impact web applications at Critical Mass, including tools for Nissan and Infiniti. I have spent my career turning complex front-end and full-stack problems into software that is fast, secure and easy to maintain.

Outside work I build AI-assisted tools on my own infrastructure.
