Hi! I'm Greg.

I'm fascinated by how people use the internet to connect with each other

I love creating things that take on a life of their own

I make robots

I'm an engineer because some awesome mentors taught me how to build robots in high school

Now I help run a website to support the FIRST Robotics community

I went to Olin College

Olin is a 300 student engineering college outside Boston

I learned how engineering, design, and entrepreneurship enable you to imagine what has never been and do whatever it takes to make it happen

I work at Facebook

I've always been interested in how people connect through technology, so now I work on making that easier for more people than ever before
