I had a nineteen week deadline to create a fund management tool to meet federal regulations. The workflow and UI were already laid out by a design team and well done.
I reverse-engineered their database structure into a class diagram and drew up this high-level design, derived java classes and wrote XLST pages for an unusual UI library. I worked overtime and on Saturdays to meet the timeline goal. The project was successful but one workflow module had some issues which we didn't have time to rework.
