My responsibilities included the development a spectrum analyzer for use by field Comcast technicians to assist them in troubleshooting customer cable modem issues. I developed a front-end web client which was accessed on iPads, using AngularJS, jQuery, HTML5, WebSockets, D3.js, and CSS3.I also developed backend services for this web client using RESTful web services and JMS messaging using RabbitMQ.

My responsiblities included the development of the user interface and middleware of one of the Clinical Informatics and Decision Support department's flagship products, an automated ordering system which was deployed in Kaiser clinics throughout the Colorado region. The technology stack I used was Java, JSP, JSTL, jQuery, CSS, Struts 1.2, SQL, and Hibernate. Among the several applications I developed while at this position, were an application to allow physicians to submit correction requests to ailments they were seeing on a patient's summary, an enrollment system which was the face of the automated ordering project, and an application to allow physicians to suppress the display and auto ordering of ailments for particular reasons.

My responsibilities included the development and maintenance of a JAX-WS web service, which served as a middle layer for many of the firm's voice services, including TeleBroker and Schwab By Phone. The technology stack used was JAX-WS, multi-threaded Java, and JAXB. Another project I architected and developed was a dashboard used to display Key Performance Indicators to Schwab executives. The technology stack used on that project was Flex 4.5, WebSphere, Spring, and BlazeDS.

Developed and maintained the customer facing web site directv.com using technologies such as the ATG custom JSP tag library, Prototype Javascript framework, Ajax, CSS, and Java.
