I am responsible for leveraging technology to streamline and improve the execution of Confidential services and business strategies. In this role I work with business leads and associates to identify requirements, design software solutions within the enterprise infrastructure as well as identifying risks and mitigations. Other responsibilities included thought-leadership on development best practices and mentoring of software development staff. Recent projects include the following:
• Design and development of web information portal for use by Confidential call centers, government and partner affiliates. Portal integrates beneficiary data from diverse sources for current plan, enrollment, demographics, claims, medical referrals/authorizations, contact history, instant messaging (online chat), self-service transactions, emails and other communications. System is n-tiered and distributed across internal and external (DMZ) web farms. Middle tier utilizes (MS) MVC which integrates data from web services (WCF), SQL Server and DB2 as well as services from partner companies. Front end is rich internet application compatible with all major browsers and assistive technology (e.g., JAWS) utilizing HTML5, JavaScript and jQuery.
• Lead architect responsible for transitioning all web applications and web services for the enterprise from Windows Server 2003 to 2008 r2. Applications migrated from current server farms to new topology of 50+ web and application servers. Migration involved several hundred applications: legacy asp, .NET (framework 1.1 - 4.5), IBM WebSphere, old style (asmx) services, WCF services, MTS/COM+. Responsibilities included working through compatibility/upgrade issues with teams of Confidential developers and assigning/ coordinating the work of various infrastructure groups for network routing/firewall, IIS 7.x configuration and security.
