Role: Architect/Tech Lead

Architect and Tech Lead at the Texas Workers Compensation Commission (TWCC). Responsible for architecting and playing a key role in developing TWCC’s next generation JEE SOA-based eBusiness platform - TXCOMP. The platform was built on a WebSphere AE 6.0 cluster of 8 nodes and consisted of various adapters & connectors that coordinate and manage all back office, business process workflow, content management, EDI, and mainframe integration. Involved in multiple areas during the project lifecycle:

 

-          Designing and developing the JEE-SOA framework using web services. Implemented a claims processing module using JAX-RPC web services  developed on Apache Axis 1.2 as the SOAP engine to process EDI and scanned data coming in from external vendors. 

 

-          Installed and configured SiteMinder r6sp5/r12.0 infrastructure (policy server, web and app server agents) using iPlanet/SunOne directory server / LDAP: Developed a comprehensive SM installation package, created LDAP forests/trees for user stores, tuned entire SiteMinder installation after performance testing. Developed Java APIs using JAAS and java.security* for processing X.509 digital certificates and  ensuring XML message integrity, authentication, and confidentiality (XML Signature & XML Encryption using the VeriSign TSIK, and Infomosaic SecureXML libraries).

This involved serializing a claim into an XML Document and then breaking up each node into a Lucene Document.  The searchable fields were stored in the index as lower case strings allowing for case insensitive searches as well as storing acronyms in upper case together with the original value of the searchable field. This indexing approach had two benefits: 1) Greatly improved speed of retrieval and display by avoiding the need to search through large numbers of documents. 2)  Saved the overhead of using a database purely to speed up searching.

 

-          Developing Talend and Mule ESB components: Developed Mule ESB components for messages, routing and workflow for integrating workflow with Talend ESB connectors. Developed Data access layer connectors for CMP EJBs and DAOs. Designing a workflow API using IBM Business Process Choreographer (WBISF) and WebSphere MQ.
