BIO
As a kid, my dream was to become an inventor. I realized that dream through software engineering and entrepreneurship. I started working early, while I was still a teenager. The first app I built for money was a CGI/Perl website, in 1999. After that, I never stopped. Somehow, I still managed to finish my BS and MBA degrees along the way. Before founding Onebrief, I was Director of Product Engineering at data.world/TX and VP of Engineering at IAC/NY.
