Selected Projects:

Oracle Life Sciences' Remote Data Capture: �Zero Foot Print� Client Oracle Life Sciences' ZFP project is a significant upgrade to their existing browser plug-in-based solution in use at Pfizer and other pharmaceuticals. The ZPF client is written entirely in Javascript and HTML (including XHTML, SVG, and VML) and features an advanced, extensible OO framework written from the ground-up to perform. It uses dual inheritance schemes; private, friend, and package member scoping; the decorator design pattern for flexible widgets; and JSON as the basis of the client-server (Ajax) protocol. My role on the team is as the �resident Javascript guru�, but I also act as the primary consult for all HTML and Browser design decisions. I introduced Oracle's developers to Firebug so we could leverage its unparalleled client-side debugging and development tools.

Stakeholder Relationship Management (SRM) for Edelman CSR, Nissan, et al. The SRM application is an industry-specific CRM application with advanced visualization and relationship tracking features for large corporations such as Nissan, Wal-Mart, and Whirlpool to manage complex relationships with NGO's. In the latest revision, a custom Ajax / DHTML OO framework replaced a fat, clunky Flash plug-in, allowing users to drag-and-drop icons representing organizations onto a coordinate map and draw relationship lines between them (like Visio). In addition, prototype was used in combination with custom widgets to enhance a ASP.Net / SQL Server architecture.

Compass Home Value (CHV) for ClickRSVP, LLC and Compass Bank CHV is a SPA (Single Page Application) that is only 160 KB (50 KB compressed, excluding graphics). CHV makes it very easy for bank customers to calculate their home equity and apply for a qualifying loan. The SPA architecture drastically decreases latency making the process extremely responsive. Eliminating delays removes a major cause of lost sales leads. Selective use of Ajax, animation, and DHTML further increased the smoothness of the application, making it feel virtually instantaneous, despite several server callbacks to perform lookups and calculations. An optional interactive (DHTML) slider allows users to find their "sweet spot" via point-and-click / drag-and-drop simplicity.
