About me

Turning complex technical problems into elegant solutions

I'm a Computer Science graduate from Western University with hands-on experience across ad-tech, fintech, and enterprise software. As a Solutions Engineer at NBCU, I work at the crossroads of client success and technical delivery, owning implementations, pre and post sale evaluations, and production reliability.

Fluent in English, Spanish, and an Intermediate in Portuguese (Brazilian). I bring both engineering rigour and clear communication to every engagement.
