Solution replaced resource-intensive manual cleansing of utility meter location data. Waterfall methodology (requirements definition document, functional specification document, wireframes/paste-ups, use cases, and system architecture/design documents). Created test plan and test cases. Created deployment plan and schedule. Responsible for all development tasks (wrote all code), daily builds, and deployments to testing. Close interaction and communication with the data cleansing working group and a business systems analyst.
Second project - successfully completed development of unfinished SharePoint/.NET work authorization management system. Entergy has a Java client used at nuclear power plants to add and update work authorizations. These work authorizations are stored in SharePoint for Nuclear Regulatory Commission compliance. I was the 6th developer to attempt to fix this cumbersome system. The completed solution included (1) a .NET Windows Service that transfers documents into SharePoint document libraries, (2) a .NET Windows Service that updates SharePoint document metadata, (3) an ASP.NET web application that facilitates creation of SharePoint document folders and uploading of documents into SharePoint, (4) an ASP.NET web application that facilitates bulk uploading of documents into staging areas for file transfer into SharePoint document libraries, and (5) a pair of ASP.NET Web Services that execute .NET SharePoint components to perform extensive file and folder operations. I wrote Oracle PL/SQL stored procedures to update tables containing new authorizations and metadata deltas. I rewrote the .NET Windows Service that accesses those Oracle tables. I wrote .NET code using the SharePoint namespaces for multiple Visual Studio projects. Each of these projects required debugging, enhancements/fixes, and integration into the delivered working solution.
