In my role, I designed and developed navigation controls, user controls, and custom controls. I gathered requirements and created prototypes for application upgrades, implementing validation controls in web forms. I coded web applications using C#, adhering to a layered architecture with ADO.NET, and designed, developed, and deployed collaboration portals and master data workflows using SharePoint Portal Server (SPS), Windows SharePoint Services (WSS), and the .NET Framework. I wrote and implemented stored procedures using SQL and utilized Data List, Data Set, Data Adapter, and Grid View to connect with SQL databases. I analyzed and implemented system features for all releases, customized SharePoint Portal Sites, and designed custom SharePoint workflows for document routing, approvals, and corrections using InfoPath 2007 and SharePoint Designer. Additionally, I developed custom forms and workflows, built user-friendly web pages using ASP.NET, AJAX, and JavaScript, and converted InfoPath forms into web-based forms for SharePoint. The environment included ASP.NET, C#, .NET 2.0, HTML, JavaScript, AJAX, CSS, SQL Server 2000, ADO.NET, Windows Server 2003, and XML.
