Project history
Development of IVR systems for automatic call handling using SIAT/iOSX call-flow systems and C/C++ libraries on Linux and Windows. Work with SQL Server, PostgreSQL, and Oracle databases; building connection layers to web servers. Writing GRXML speech grammars, Linux and shell programming, managing compiler versions and CMake configuration, version control with SVN. Lua development for a new call-flow system and writing supporting C libraries. Responsible for development, deployment, and analysis of unexpected production events.
Built a technical management application for the mining industry in C++ on Windows. Designed C++ classes to abstract and manage Access, MySQL, and PostgreSQL databases using COM objects. Evaluated and integrated computational geometry including Delaunay triangulation (CGAL, Boost.Geometry, Triangle, GPU-based options, OpenCV, VTK), surface interpolation, and union of open/closed polylines. Used Git, STL, Doxygen, CMake, and C++11 features.
Air-traffic surveillance software: C++ on Linux for encoding/decoding surveillance data according to the EUROCONTROL ASTERIX standard; Ada programming on Linux; SVN.
