Rahul served as the software development engineer on the Weather Connect (WxConnect) product line where he was responsible for a number of enhancements to the software baseline to increase functionality available to the variety of customers receiving GOES-R data through this product. He was integral to identifying and solving issues for the National Weather Service units that experienced interruption to the building of the weather product images. His program engagement, attention to quality, and technical acumen enabled the team to compare data among sites to eliminate non-contributors to the root cause, ultimately resulting in a successful root cause analysis that received direct visibility by the customer.
