Work Samples & Demos

This page contains links to some simple work samples and technical articles in FileMaker Pro, web development, and finance & investment modeling.

Note: Unfortunately, due to the complexity and extraordinary amount of work that goes into my more advanced FileMaker projects, there are not many that I can simply publicly distribute for free. I have written a personal library of very advanced recursive custom functions, a stock portfolio manager including realtime broker API integration with oAuth authentication, the below-mentioned DDR dependency analyzer, and other much more advanced FileMaker solutions that I cannot share for public download, but am happy to do a remote screenshare and demo all of it for interviewers or anyone else interested. Please contact me using the contact info at right to arrange a live demo.
