Hi, I'm Dan

I'm a full-stack Web developer in Bethesda, MD

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 Philadelphia and the New Jersey shore. I moved to the DC area in 2016.

I'm separated, and have an amazing 4 year old daughter. I enjoy playing in pinball leagues and competitions, riding e-scooters, going to baseball games, and watching the This Week in Google podcast, even though it's never actually about Google!

I'm a Software Engineer at CDK Global, working on their Roadster platform. I contribute to a product that 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 13 developers, developing the platform using the Ruby on Rails framework. I also work with the data analytics team, where I contribute on our Airflow data pipeline, allowing the business to make its decisions in a data-driven manner.
