About Dan
My background is in Web development, especially full-stack development using the Django and Ruby on Rails frameworks. I'm from Wayne, Pennsylvania and graduated Penn State in 2007. I previously lived in Bethesda, MD, and Philadelphia. I moved to the Jersey shore in 2021.
My wife Lili and I have two amazing daughters, and seeing them both embrace video games and tech has been really awesome. Personally, I love playing pinball, watching the Phillies, and listening to audiobooks about computer programming, productivity, and startup stories.
I'm a Staff Software Engineer at CDK Global, where I work on the Roadster platform. Our product makes the car-buying process easier for consumers by allowing them to get upfront pricing, and complete most of the paperwork remotely, before stepping foot into the dealership. It also makes the selling process easier for the employees at the dealership, allowing them to make more sales and improve customer satisfaction. I work alongside 25 developers, developing the platform using the Ruby on Rails framework. Recently I've been focused on our ops, specifically improving our response time and availability, and fostering engineering practices that ensure ongoing success.
