Confidential, Denver, CO

.Net Developer/Architect

Responsibilities:

• Architect and build an Oil/Gas Reserves Management module.
• The system was designed to be used by engineers and geologist to determine the remaining oil in place.
• The module compliments the generation of GIS mapping and grids for analysis.
• The module contained about 20 sophisticated views all built in C# and WPF. Telerik controls were used for charting and other features not supported by Microsoft’s libraries.
• Create and build a component to produce an Oil or Gas Well’s Decline Curve using the Hyperbolic Equation.
• The decline curve is a method used in the oil industry to estimate the remaining production for a given well.
• To determine the values used in the Hyperbolic Equation I used Microsoft’s Solver Foundation. I built three versions of the component.
• The first version I built was for a WPF client/server implementation.
• The second version was built targeting a WPF thin client with the business logic residing on the server as middleware.
• I used WCF to build a TCP/Binary communications channel to send requests/responses to and from the middleware.
• Lastly, I built a version of the component in Silverlight.
• The Silverlight component’s requests were fulfilled by an OData Service with the data being marshalled in JSON Lite.
• The implementation was built using an n-tiered architecture which allowed the same business logic class to be used in all three versions of the component.
• If required, the host can also expose the business logic to external consumers via a SOA Http/Soap interface by simply adding an additional WCF binding definition.

Confidential, Loveland, CO

.Net Developer/Architect

Responsibilities:

• Repair a new Silverlight Payroll System that was over a year behind schedule.
• The existing Silverlight reporting solution was a failure so I changed the architecture of the application to inject SSRS.
• With SSRS implemented the reporting performance, quality of reports and exports exceeded all expectations.
• I also repaired a large number of bugs/mistakes in the usage of Unity, MVVM and RIA Services that were causing grave errors to occur.
• The performance of the Silverlight User Interface was poor due to the complex processes that were being performed to present data.
• I moved these complex processes to background threads on the server.
• The performance of the UI went from 5 minutes to present a view to less than 2 seconds. In the end, all fixes were released to a very happy user base of approx. 40,000 users.
• My efforts saved a multimillion dollar project from being dumped.
• Repair a new Sales Representative Commissions Payment Application.
• Again, I was handed off an application that was behind schedule from another development team.
• The Asp.net UI was only 30% complete and was riddled with bugs.
• I created a couple new subsystems as MEF Parts in Silverlight to complement the existing UI.
• Next I replaced the Asp.net shell and menu system with a new framework written in Silverlight. I quickly ported the remaining Asp.net pages to Silverlight views and created an additional eight missing views.
• RIA Domain Services were developed on the backend to support the database maintenance requests of the UI.
• The system was designed to include a dozen complex SSRS reports that I built and seamless integrated into the Silverlight application.
• A Windows Service was created to execute long running processes that calculated commissions real-time.
• The UI communicated to the Windows Service using WCF Services that support high speed TCP and binary data transfers.
• To complete the task a large number of database design changes were required along with a great deal of optimization to achieve acceptable performance.
• Teach other developers: Taught group classes on MVVM, Reporting Services and Silverlight. For these classes I created a lesson plan and a complete software example of how to implement Reporting Services into a Silverlight solution. To teach other developers MEF and the usage of SHELLS I created a prototype of the existing application using newer design patterns.
