Senior .Net Architect / Technical Lead

Responsibilities:

• Senior .NET Architect and technical lead responsible for the architecture and development of an application shell for Microsoft SQL Reporting Services. This application shell enables both Web clients and fat/smart clients to access and customize reports managed by SQL Reporting Services. I developed an application services tier that wraps the Reporting Services Web Service and provides an
• Authentication and Authorization Extension to enable Web clients (the current out-of-the-box version of Reporting Services only supports Integrated NT Authentication). The report customization capabilities that are enabled by the my application services tier permit end users to select a report and prune (remove) columns and publish a new report in their own private “sandbox” without the need for the Visual Studio Development environment. For this solution I developed server side code in C# and stored procedures in Microsoft T-SQL.

Confidential

Senior .Net Architect / Technical Lead

Responsibilities:

• Senior .NET Architect, technical lead, and principal developer responsible for the architecture and development of a Value-At-Risk (VaR) computational engine and user interface for the energy trading sector. This Risk System is designed to leverage Microsoft’s .Net Smart Client architecture. The user interface is coded in C# and takes full advantage of inheritable WinForms and User Controls.
• The GUI communicates with the server tier for database access via .NET Remote Objects. The server based computational engine gets launched by the GUI and then splits the task of computing the results into smaller tasks which in turn are distributed across a server farm or computational computer grid via Remote Objects. Using remote Delegates, feedback in the form of progress, statistics and results is returned, in real time, to any/all monitoring users during the duration of the run. Users may detach and reattach to the run anytime during or after completion to view progress and results. Included in the implementation is a data abstraction layer built on top of ADO.NET that facilitates the switching of the data source from Oracle to MS SQL Server with a flip of a runtime configuration switch. For this solution I developed stored procedures in Microsoft T-SQL and Oracle PL/SQL to provide access to business entities and to implement business rules.

Project Manager / Software Architect / Lead Developer

Responsibilities:

• Project Manager, Software Architect, and Lead Developer under contract to Xcellenet, an Atlanta based corporation specializing in Networking and Remote Access solutions. I was responsible for the Architecture and Development of a Distributed Resource Manager that enables the locking, for exclusive use, of a pseudo resource across multiple computer systems on a network. I was also responsible for the Architecture and Development of an Internet HTTP Proxy to enable off-line browsing of Web pages as well as the Architecture and Development of an Internet Spider.
• The Web content discovered by the Spider was saved on the local server in a cache and later “pushed” to client systems as they connect. The Distributed Resource Manager, HTTP Proxy, and Internet Spider were designed to utilize a common COM/DCOM/Win32 framework that I was responsible for architecting and developing. This framework consists of a suite of over 400 COM based C++ classes to encapsulate the MAPI and Win32 API and to provide a queue based worker thread model for processing and scalability. As tasks are added to the task queues, worker threads are dynamically scheduled to process the tasks. These projects required extensive knowledge of COM/DCOM, MAPI, Networking, Internet protocols, multi-threading and other server scalability issues.
