> Senior Software Engineer II at HubSpot

Location: Austin, Texas, United States
Profile: https://flows.cv/ernesto

I've spent the last decade building frontend systems across product and platform, at both startups and enterprise. Early in my career I joined a small restaurant tech company as their first engineer in a new office, built the team from scratch, and shipped product simultaneously. Since then I've worked on systems that have reached millions of customers, led architectural initiatives with executive visibility, mentored engineers at every level, and built infrastructure used by thousands of engineers across thousands of apps. I'm always looking for ways to ship better work faster, including how AI fits into that, without cutting corners or compromising on quality. I believe in writing good code, building A+ teams, and solving problems that are actually hard.
