PROFESSIONAL EXPERIENCE:
1. HomeHealthTek 05/09 to 09/11
Free Lance Project
1. Designed and implemented a full featured web based application for Long Term Health Care Facilities taking requirements from Nurses and Administrators. The goal was to create a program that would help shift nurses do their job, help them to avoid mistakes, keep them up to date on what tasks need to be done and be easy to use. I also wanted the program to be give complete visibility to the DON into the status of the work assigned to the shift nurses. The program was also to give the Medical Records person, the Pharmacist and the Facility Administrator visibility into pertinent data. Architectural features included: (1) Database operations were built with Spring JDBC and could be called from one line of Java Code. All database CRUD operations and create operations were code generated from XML and Join database calls were put in an XML file (2) javascript based front end uses ordered AJAX calls to give rich application effect with minimal page refreshes, (3) front end input forms built from XML or dynamically in javascript as needed, (4) all client information tables where configured from XML and loaded via JSON from AJAX calls to database. ( J2EE, Tomcat 6.0, MySql, Spring JDBC, iText and PDFBox for pdf display, Javascript, DWR for Ajax, JSON, jQuery, JavaCC, Apache-Solr for Medication Selection from NDC Database, Yui Compressor ).
Client: Orange County Superior Court 03/07 to 05/09
Senior Consultant
1. Designed and implemented the Probate Kiosk application. This application included a web component in which users would view and select pages from lists of pdf documents. A standalone swing application was developed for the counter where documents would be managed, printed and paid for.( J2EE, Oracle, Spring JDBC, iText and jPDFImage for pdf display, Java Swing with NetBeans gui builder, DWR for Ajax, JSON).
2. Redesigned and implemented existing internal and external web applications for Civil, Family Law, Probate and Small Claims. All of these applications used a Struts MVC framework and database calls based on Spring JDBC. Client side paging of large amounts of table data was greatly speeded up by using JavaScript objects to manage the data.
Client: Brilliant Blue 11/06 to 03/07
