PROFESSIONAL EXPERIENCE:

Senior Programmer/Analyst

Confidential, Silver Spring, MD

Responsibilities:

• Designing/developing Single Sign-On(SSO) project in Department of State Foreign Service Institute(DOS/FSI) using Web Forms, Server Controls, User Controls, HTML, XML, C#.NET, ASP.NET, ADO.NET, Ajax, jQuery, Web Service, Active Directory Search, VS.NET 2008/2010, VSS, ER model, Stored Procedures, Cursors, Triggers, User-Defined Function, and SQL Server 2005 in Windows XP Prof /Windows 2003 with IIS. SSO authenticates a user in order to access a tool/application without an extra login process if the user is logged into the DOS network and has permission to use the tool/application. SSO can be reused on various FSI applications, which saves applications development time and offers a central place to manage user/role information, which in turn benefits the FSI Help Desk.
• Working as a Team Project Collection administrator for Team Foundation Server(TFS) 2010 in DOS/FSI. Configured the FSIEXProjects collection and its Show Project Portal and Reports Site. Created new projects in TFS or inputted projects form VSS to TFS.
• Working as a Visual SourceSafe(VSS) Admin in DOS/FSI. Consolidated multiple Visual SourceSafe (VSS) databases from different locations (servers) into one file server. Reorganized/reconstructed Projects in those VSS databases to make them more easily for users to use and manage.

• Designed/developed EventViewer web application in DOS/FSI using C#.NET, ASP.NET, Log Parser COM component, Ajax, SqlBulkCopy, ObjectDataSource, ER model, Stored Procedures (one of them returns a paged and sorted DataSet). EventViewer inputs large data (a log file in about 100,000 KB) into database in a few minutes through SqlBulkCopy, and, efficiently, lists log event info from couple of million records in GridView page by page through the paged and sorted DataSet.
• Implemented Salted Hash Password in FSI Survey application (classical ASP) in DOS/FSI using SQL Server methods HashBytes() and newid() in stored procedures.
• Relayed Surveys, ADGalLoad, and other .NET applications in DOS/FSI from one developer to another. Located/verified all resources of those applications, tested their source codes, and knew how to use/run those applications in very short time.
• Developed/implemented Crystal reports in SLS Express application in DOS/FSI using CrystalReportResource to load and set ReportDocument dynamically in runtime, and Response (BinaryWrite) method to export customized Crystal reports. In this way, we reduce navigation/clicking times to have a Crystal report in a proper file format, and treat *.rpt file as a template not regarding a specific database.
• Designed/implemented Fees and User Admin (Tab) in SLS Budget Tracker application in DOS/FSI using ASP.NET, VB.NET, SqlDataSource, and GridView (with client/server side validation), and web service (to sync user’s roles with the user’s role assignment in SSO).
