An Insider's view of Rally Health

What does your typical day look like?

The first thing I do in the office is grab breakfast. I go through my email, greet my team, and check my schedule. Then I get to coding! We have a daily engineering stand up, a brief meeting where the team shares what they’re doing. Then after lunch, I finish up my meetings and coding work, then do some collaboration before wrapping up.

Software Engineer

What projects are you most excited about?

I'm working on a project to create a streamlined experience for consumer-based individual health records (IHR). IHR focuses on consumer engagement, actionable health information, physician data sharing and value-based incentives.
