Worked on Radio Dispatch Console systems, primarily an IP based console system. Updated exisiting code to conform to coding standards. Designed and wrote most of the implementation for a text messaging and subscriber radio presence system for the IP Radio Console, using an Erlang server with C++ clients.Converted C++ audio processing from floating point arithmetic to fixed point, optimizing, improving audio quality, improving reliability of tone detection, fixing bugs in generation of RTP packets for G.711 codec. In all CPU usage on the device was resuced from 90%+ to ~25%.Designed and implemented new TCP based control protocol for linux-based radio gateway embedded devices. Reimplemented parsing of XML configuration parsing on the using libxml2 instead of xerces and Altova generated code. This reduced the parsing time on the embedded devices from 30 seconds or more to less than a second, as well as significantly reducing disk space usage, and allowed the same code to be used on both Windows and Linux.Made extensive updates to the C# based system configuration utility.Also worked on many other Windows C++ based components of the systemCreated or worked on several development support tools in Python.Created guidelines for Modern C++ development based on the C++ Core Guidelines created by Bjarne Stroustrup and Herb Sutter.Used Visual Studio 2008, 2010, 2012, 2013 and 2015, gcc 3.3, 4.7 and 4.9. Used boost and libxml2 libraries. Used Perforce version control and Jira bug tracking.

Converted an Access based database system to an Oracle back-end. Built a Flash client interfacing with web services through XML.

Built Windows and Mac client applications to work with Axentra’s NAS (Network-Attached Storage) based media server application, primarily working in C++ and Objective C. Worked with Mac OS 10.2 – 10.5, Carbon and Cocoa APIs, Windows XP and Vista. Used Visual Studio .NET, Xcode, and wxWidgets.Automated the build process for setup CD, using makefiles for make and nmake, as well as batch files and UNIX shell scripts.Built Flash based backup UI module to backup NAS Contents to USB or online storage. (Flex / Actionscript). Built Linux daemon (with C++) to execute background jobs including backup / restore, photo uploading for online printing and online sharing. Used libxml2, libcurl, and XML schemas.Worked on the installer CD (dual Mac/Windows platform) using C++, HTML, Mozilla, UPnP and ICMP.Used CVS And SVN source control and Bugzilla bug tracking.

Part of the team building and running automated test suites for Microsoft Commerce Server. Used C#, Visual Basic, and VBScript to build test cases. Used Visual Studio .NET and worked with SQL Server; and 2008 (pre-release).

Worked with one other developer to build an internal utility to track smartcard order statuses. Used Visual C++ and PC/SC.Built a plug-in to allow the use of Active Directory or any other LDAP compliant directory in place of a relational database for an ID Card design and production application. Used Visual C++ and LDAP, and ADO.Built new UI components using C#, .NET 2.0 and Windows Forms in Visual Studio .NET for the upcoming release of the same ID Card software.Used SourceSafe source control.

Part of the team that designed and developed the Biometric Engine server, allowing the use of multiple biometric algorithms through a single API. This used TCP/IP communication, and a SQL Server or Oracle database.Built a new versions of the low end ID Card design application in Visual Basic. Built several image capture and biometric data capture plug-ins for various cameras, fingerprint scanners and finger and palm vein scanners (in C++).Designed and coded the first implementation of the Imageware Card Management system using C++, XML, SQL Server and Windows services.Implemented several new features and bug fixes for an MS Access based ID Card design application.Created certified PIV (Personal Identity Verification) middleware DLL in C++, using PC/SC.Created card movement plugin architecture for card printers and implemented several of these plugins.Created several other prototype and demo applications using a variety of technologies including PC/SC and various Smartcard technologies, C#, Visual Basic, and various RDBMS’s.Used Visual C++ 6, 2003, 2005 and Visual Basic depending on the project. Used SQL Server (several versions up to 2005), Oracle 10g and AccessUsed MKS SI version control.

Part of the team, and later the technical lead for the team, that developed, with Visual C++ on Windows and CodeWarrior C++ on Macintosh, an image management application, which searched local drives for images, generated thumbnails, and allowed them to be classified, assigned keywords, etc.Developed an export wizard to manipulate both raster and vector images, on both Windows and Macintosh platforms and export them to other applications in a variety of formats, using LEADTOOLS on the Widows platform.Used Mac OS 9 and 10.0-10.2 (Carbon API), and Windows 95 – XP.Worked with MFC and Windows GDI extensively.Worked on a prototype server (in Java) for Internet-based image searching and sales. Part of the team that developed the client component in Visual C++. This included designing and implementing a search engine that could perform high speed of images both on the Hemera server and on the user’s local hard drive, and generation and management of thumbnail images. Primary developer for the final versions of the client. Used http and https (using openssl) through sockets on Windows and Mac OS X.Also developed various internal utilities, using C++, Visual Basic, MS Access, Oracle 9i and ODBC.

Part of the development team for the ForeMost records management application. Initially responsible for the database schema and the interface, in Visual C++, to a variety of DBMS’s, including SQL Server, Oracle and Sybase. Designed and built a DCOM based middleware server for a three tier version of ForeMost. This was implemented as a Windows Service, in Visual C++, using ODBC to access SQL Server, Oracle or Sybase.Developed a number of related utility programs, such as data import and database upgrade and conversion tools, using Visual C++, ODBC, etc.Built several gateways to integrate with other applications such as Microsoft Word and Excel, Lotus Notes, and FormFlow, using the native scripting languages as well as C++.

Built a job tracking system in MS Access and Visual Basic.Built ‘pre-flight’ tools in Visual C++, and Visual Basic to ensure that customer files met the required specifications (e.g. images in CMYK colourspace, 300 dpi resolution, etc.)Wrote various tools for specific customer recurring jobs, automating the production of desktop publishing documents from raw customer data. Used a variety of technologies, such as VB, C++, and MS Word macros.

Designed and programmed software in C. Prepared interactive multimedia presentations on an Amiga platform using Amigavision.
