Engineer, founder, builder. I currently lead engineering at Numa — a Silicon Valley startup shipping AI-powered automation for the auto industry. Before Numa I co-founded two Brazilian tech companies and spent the better part of a decade learning what it actually takes to put software in front of people who depend on it.
I care about three things: shipping, architecture that gets out of the way, and mentoring teams to ship faster.
