PROFESSIONAL EXPERIENCE:

Confidential

Enterprise Architecture and Development Team Manager

Responsibilities:

  • Building Advanced Messaging Queueing Protocol service stack to enable transfer of data to disparate software application consumers. Portions of this code are written in C++ with the majority of the code in C# running in .Net Framework 4.52. Currently working with SQL Server 2014 including new “in-memory” tables.
  • Use of the Health and Human Services Enterprise Performance Life cycle (EP:LC) process from software solution ignition through its sun downing. The process is composed of 10 phases and is similar to TOGAF .  
  • I am heading an effort to refactor a large scale system that allows CDC employees to review expenditures on a global scale. The General Ledger runs in Oracle Financials with several custom modules specific to CDC and government usage. 
  • The user interface is currently written in AJAX/ASP.Net. This is being migrated to WPF. 
  • The refactored system will employ web service engines (my specialty) in order to communicate between applications and components. Due to previous issues with preparing data warehouse scale data for the review process, previously existing SQL Server jobs will be implemented using Windows Services with intelligent control to prevent failure during heavy load. 
  • The refactored system is load balanced. This involves the heavy usage of threading currently being implemented on .Net 4.0. As such, features of the Parallel Task Library are being employed.
  • In September 2014 work in Java was added to build a framework that can touch and authenticate against a variety of directory servers including Microsoft AD, Apache DS, Fedora DS, generic LDAP, Novelle Directory, Open DS, Open LDAP, OpenLDAPRfc2307, RFC2307, and .Sun ONE. I had previously performed extensive work with Sun One. This work is in support of content management.

Independent Consultant

Confidential

Responsibilities:
  • I have worked as an independent consultant since December of 2012. In this work I have acted as an architect/developer for multi-threaded transaction processing applications supporting MVC front ends. The work was focused on .Net 4.5 using Visual Studio 2012 running against Windows Server 2012/SQL Server 2012.
  • Performed primary architecture work for Windows 7 Phone applications.
  • In this work my focus is at the enterprise level where large scale backend infrastructure is employed.

Environment: C#, Visual Studio 2012, Web Services, MVC4, Oracle, Mainframe DB2, and SQL Server 2008/2012, TDD, WinCE and Windows 7 Phone.

Confidential

Enterprise Systems Architect

Responsibilities:
  • Created an enterprise architecture moving existing legacy systems written in Visual Basic 6.0, Visual FoxPro 2.5, and paper systems to a new model composed of C# based Windows services as the data layer, WPF user interfaces, and an OPC server deployed to tie machine level systems to the architecture and upstream to SAP. (An MES architecture).
  • The business layer ties to the MES system using BizTalk. The BizTalk Rete engine is used within the core MES for logical representation.
  • During this period a framework consisting of some 80,000 lines of C# and C++ code was composed. At the machine layer, some 30,000 lines of code were produced. Clients PLCs were Allen-Bradley. The OPC server was Kepware.
  • Brought on at OFS Fitel/OFS Optics based upon previous experience in the manufacturing sector and specifically work with manufacturing execution systems.

Environment: C#, C++, SAP ECC 7.0, WCF, WPF, Oracle, TDD, WinCE for embedded systems in a Lean/Six Sigma environment.

Confidential

Operational Systems Architect

Responsibilities:
  • The primary languages used were C# and C++, with some SQL. ‘Platforms’ were web, desktop app, backend, and mobile. Backend systems were mainframe and Unix.
  • The front-end travel booking system was operated by TravelPort and other GDS profile vendors
  • Most significant work from a developer’s perspective was the development of C# threading tools used in architecture of multi-threaded applications as well as performance diagnostics with issues such as races and deadlocks. This work was being performed in .Net 4.0 and in applications using System.Threading Tasks.
  • New software development conducted using the rational process. The interface between the mainframes and server/desktop level applications was Tibco Rendezvous. Most systems were constructed in a SOA pattern with prolific use of web services between Delta and its various vendors.
  • Employed portions of the Rational Process. The primary artifacts used by developers are class diagrams and threading models (Non-RUP).
  • Systems were real-time and often integrated with FAA systems as a secondary data source.
  • The focus of systems was eventing data and messaging within the real-time systems realm.

Environment: C#, C++, DB2, Tibco, WCF)

Confidential

WPF/MVC Developer

Responsibilities:
  • Performed C# applications development for the company’s identity client/server personal information search application. The application is comprised of a WPF/WCF based enterprise web console and a C++ based search client, backed by MS SQL Server 2008 (C++ on Windows, C on Mac, and C++ on Linux. SQLite used for data transfer through ActiveSync.) Application used the .Net 4.0 framework and the MVC Release 2 framework (Some MVVM also used). Portions of the application used Ext.net/AJAX. The client installed as both a service and an executable application that can be started by the service. IDF software uses Microsoft Enterprise Library and is a heavy user of Unity for IoC.
  • Work focused on building a distributed version of the application where the workload was determined at the enterprise console level and based on this information clients were loaded remotely individual PCs within the corporate domain.
  • In addition, constructed a series of WPF Logical Tree manipulators as well as custom content presenters. This particular work enables injection much like is possible with JavaScript.

Software Developer/Architect

  • Applications included data management applications, risk assessment applications, sheet generation, and an ArcMap extensions used for visual editing of pipeline data using linear referencing. Current applications used Telerik Controls in a modified MVVM pattern due to their level of complexity and need to “skin” applications. Web front-end applications were being moved to Prism 2.2 and Silverlight 4. (Based upon the original Composite Application Guidance recommendations issued by Microsoft.)
  • Applications ran against wither ArcGIS 9.2 or ArcGIS 9.3.1 with work in progress on ArcGIS release 10. Applications were written in Visual Basic and C#, with the greater portion being in C#. Work was underway to move applications to Silverlight 4.0 using the ESRI Silverlight API. For the ArcGIS release, 10 applications feature editing used ESRI’s new feature service. Moving to Silverlight 4.0 was extremely critical for web based GIS applications because these applications are RIA or Rich Internet Applications where state was difficult to maintain in the asynchronous web environment. Thus RIA Services introduced in .Net 3.5 and expanded in .Net 4.0/Silverlight were critical.

Environment: WPF/WCF with ASP.Net and Winforms. Patterns include Structured MVVM, MVC, and PRISM libraries with Silverlight.

  • Architected and developed a LINQ/WCF based application used to build “discovery” type queries against data stores. The application was developed using SQL Server 2008, Oracle, other data sources, and Visual Studio 2008 (.Net 3.5). Hands on coding effort involved around 80% of my billable time.
  • Developed while also managing developers working on various DoD contracts in the Georgia region. These efforts spanned technologies including old C++ and VB based ASP applications through current .Net 3.5 applications using AJAX and LINQ. Focus areas included SAP system support for government entities; data driven applications; GIS applications (ArcGIS); manpower applications; and general informational websites. All new development projects (except SAP work) were driven using IBM’s Rational Tools. Some of the projects combined the old technologies with new, i.e. ASP and ASP.Net.
  • Generated the action plan for maintaining a large portal site written using VB based ASP on the portal and ASP.Net in various client modules. Maintained specific VB/ASP pages while directing the coding efforts of other developers. (50% hands-on/50% management and design)

The app used an IBM load balancer running on AIX that spread the workload across the web farm. C++ services running on NT 4.0 backed a web based authoring tool for publication of documents in the system that was called Comperio (A Price Waterhouse Coopers product.)
