Senior Software Engineer Confidential

• BI is a company that monitors individuals using GPS, RF, and Breathalyzer and Voice Identification technologies for various federal, state, county and city agencies. To accomplish this mission, BI has created its own proprietary hardware and software. The customer-facing applications were three web applications while the internal monitoring software was a Windows application. The associated production databases were designed for a high volume of real time-transactions between various parts of the system.
• First project was to design and create a Volume Simulator to send data to a processor that would normally be forwarded by a listener from field monitoring devices. The simulator allows BI to test its processors prior to introduction into the production environment with any number of virtual units calling in after any changes are made to the code. Designed and implemented a C Windows Forms application to create all of the data a simulation would need. Also designed and created a C multi-threaded Windows Service did the actual job of presenting the simulated data to the processors at the appropriate time. A SQL Server simulation database was designed and implemented using the production database as a template.
• Designed and implemented a Windows Forms application for the unit testing of the processors with specific test cases to prevent problems encountered in production whenever changes to the processor codebase had been made. Also, reduced the time that QA's spent on testing the processors. Routinely designed and created small applications for QA use when an interface for testing new features did not exist. Made suggestions about what areas to concentrate testing effort on when new functionality was added or code had been modified.
• Participated in the architecture planning for a major revision of the ExacuTrack web application. Once the design had been approved, helped implement the changes required in C and VB.NET code, html, Javascript, database tables and stored procedures for a release
• Team Lead for Mobile applications. After gathering the user requirements, designed and implemented two new Windows Mobile 5.0 web applications that enhanced and extended BI's ExacuTrack and GuardWare products. After their release in to production, these applications spawned user groups within various agencies. Communicated with these user groups by phone conference meetings to address their concerns and suggestions.
• Team Lead on different phases of BI's new integrated web application, TotalAccess . Investigated various Ajax enabled web toolkits and narrowed the choices down to three for the team to review. Did the initial conversion of existing aspx pages into the new user interface framework based Telerik's Rad Controls and Ajax. Then created and implemented a user interface and workflow design that took take advantage of the new user interface metaphor provided by using the Telerik toolkit.
• Designed and implemented a new multi-threaded Windows service that allowed base units to call into the ExacuTrack application, TotalAccess. Later, designed and created a new multi-threaded Windows service that re-directs calls from base units intended for the legacy application into the new application, TotalAccess. In creating this service, BI was able to avoid having to recall base units in the field for factory re-programming of phone numbers when an agency desired to move from the legacy to the TotalAccess system.
• As part of my experience with the full software development life cycle SDLC , have experience in Waterfall, Extreme Programming XP and Agile environments. Experienced writing requirements, design and release to production documents. Also, have experience using MS Project to create and update schedules. Use of MS Visio for design plans.
• While I am familiar with the functional programming style, my entire career has been spent designing and implementing software code using the object oriented analysis, design and programming metaphors.
• Summary of involvement with various project types while employed at this company includes:
• The design and creation of Web, Mobile 5.0 Web and Windows Forms applications.
• The design and implementation of Web and Windows services. Most of the Windows services were multi- threaded and used sockets to communicate with other entities. These were generally written in C , but one was in C and a couple were written in VB.NET .The services included listeners for incoming messages on either an IP port or banks of modems. Another group of services were the processors for generating events and alerts based on the incoming information.
• Extensive use of SQL Server on a day to day basis.
• Conversion of Visual Basic based Windows services into C based equivalents.

Tools used: Visual C , Visual Basic.NET, Visual C , Telerik RAD Controls, Virtual Earth, MapPoint, Java Topology Suite, DockPanel Suite, SQL Server Enterprise Manager, Team Foundation Server, Visual SourceSafe, PVCS and PVCS Tracker.

• Hired to take over several existing development projects CompassTrac, CompassTrac Mobile, CompassWorks and CompassTrac Report Module that were written in VB6 and needed to be moved to .NET equivalents. These products were designed to be the gps-based positioning, speed and status-reporting components of an Automatic Vehicle Location system.
• First assigned task was to fix the high priority issues with the applications. Then, converted the applications to .NET after new product designs were approved and then worked on product enhancements. New products and services were designed and implemented in C using object oriented techniques. Designed and implemented a new application CompassRespond Administration Module . The purpose of this new application was to be the core of an application and data update mechanism for similar to the Windows Update. It downloaded CompassCom executables and ESRI based map data files to a user's computer and then requested that the application be stopped while the updates were made. Was in the process of replacing ESRI MapObjects with ArcObjects in the existing applications at end of tenure at CompassCom. Also, was experimenting with ArcGIS Server generated maps in a prototype ASP.NET web application.
