Hey, I'm Ryan Mahan!

I love coding, hiking, and NPR podcasts. At Optum, I am a full stack web developer and scrum master for a team focused on creating cost saving solutions for outdated practices within UnitedHealth Care. At Home, I take care of two dogs, attempt DIY projects, and try to find time to contribute to open-source projects.
