Sr. Data Warehouse Engineer


I have never come across a project manager like John in my entire career, who is highly technical and understands business really well. He was the one who designed the whole GSA data model. I would like to give kudos to John for making this project successful and getting it delivered in a timely fashion. Personality wise, he is great to get along with, just that you have to put up with his Hawaiian shirts! Just Kidding. I would love to work with him again in future and wish him success in his future endeavors.
