control, dependency injection, and centralization and sharing of code elements.

Cisco Systems, Inc. 7/2005 –11/2009

C# WinForms / WPF Software Developer

Designed and built the Customer Analytics Tool (“CAT”), a C# WinForms app that distributed sales opportunities to field sales staff. Tied to back-end MS SQL Server database using ADO.Net. Implemented multi-threading to improve user experience and speed up asynchronous access. Provided option to store data offline in safely encrypted files. Wrote user customizations locally using XML and SOAP. Received rave reviews from managers and salespeople for the user-friendliness of the interface, as well as its ability to present mass amounts of data in a simple, clear way.

Migrated the CAT tool to WPF under Dot Net 3.5. Implemented MVVM architecture using XAML for the View and an observable collection for the View Model including all required bindings, properties, and routed commands. Took advantage of WPF’s dependency and attached properties, styles, triggers, control and data templates, and routed events.

Planned and coded Cisco Apps (“CAPPS”), a C# WinForms program installation and launching platform, for the Marketing Intelligence group. This program produced only one desktop icon because it acted as a min-desktop of its own. It allowed Cisco to build “quick apps” that could be developed in a few weeks rather than 6-12 months. Code was shared between applications. Created a custom thread pool to improve management and efficiency of worker threads. Data source was MS SQL Server.

Created a comprehensive customer mapping tool that linked to millions of customer records in an MS SQL Server database. Showed customer locations on a Virtual Earth mash-up. The tool could be used to display geo information about any data table.

Inherited and significantly improved third-party libraries at various phases and for unique departmental requirements: Syncfusion initially, then DevExpress, and finally Telerik.

Performed all unit testing, debugging and post-release support.
