Professional Experience

Dyno Nobel, Salt Lake City, UT
April, 2017 – present
  Senior IT Consultant
  Preload software for mine engineers to design the optimal blast load based on drill rock hardness and face profile data. The software automatically splits a hole into load segments to use optimal product density and/or weight for each segment to export the data for load truck computer. Preload is capable to import blast data provided in variety of formats such as csv, xlsx, txt, xml, IREDES, mdb, dxf to integrate with internal data model using persistent fields mapping. Load Profiles created based on vertical/horizontal hardness and face burdens help to create blast load data in a few clicks. Both 2D and 3D blast diagram modes are supported. C#, Visual Studio, WPF, SkiaSharp, UrhoSharp, MVVM Light, NLog. Screenshots.
  Dyno Shot Layout software to use on mobile devices for mining engineers, blasters and drillers to design a blast by entering holes pattern, geometry, location and timing data. The software operates in 3 modes - Shot Layout, Drill Log and Hole Log. In Drill Log mode all planned holes created in Shot Layout mode have the data how they have been drilled including actual depth, rock type and drilling conditions. Drill Log mode accepts products data and the way how each hole has been loaded. The report prepared in PDF format shows differences between planned planed and drilled data for each hole along with 2D blast diagram. The software is integrated with company's central database to import/export data using REST API and run under iOS, Android and Windows(UWP). C#, Visual Studio, Xamarin, SkiaSharp, XML, AppCenter.
