John Kellgren

Senior Application & Database (Access, QuickBase, SQL) Architect


Falls Church, United States


My main objective is two-fold: 1) To apply the combination of my software application architectural skills, my database architectural skills, and my administrative skills together with the Business Analysis experience that I have accumulated over 25+ years. 2) To allow my business clients the breathing room to know that they will only have to address the tasks of defining and producing an efficient and working on-line and local user-oriented Application.

    QuickBase Time and Attendance Solution
    Job dragged on and on due to not having specific requirements. One of our managers kept changing requirements during the project. It was a disaster. John is an amazing programmer, but we needed to give him firm requirements from the beginning. It was also our mistake to not make this a fixed price job with specific requirements. It cost 3X to 4X what we thought it would, and we never did manage to get it off the ground.
