Windows desktop application running on kiosks installed on facility premises. This is a windows form application written in C# for .NET 2.0, serves for inmates and provides all available services provided by JPay. Kiosk is able to capture/stream picture/video from webcam, send/receive/display/compose text message with or without attachment, download mp3 files from JPay servers, upload mp3 files to mp3 players. Module responsible for file uploads to mp3 player is written in C and referenced using interop from C# application. I fixed multiple pages (architecture of kiosk is made similar to web experience where every forms appears as a new page with backward availability) including C# backend, web services, stored procedures, Flash application for video visitation (flash application embedded into kiosk inside embedded web browser control). Web application for system setup and management implemented as C# ASP.NET 4 web forms project. Application consists of data layer, business layer and presentation layer. Data layer and business layer implemented as separated assemblies and shared across multiple projects. Some parts of business layer implemented as WCF services. Web application uses Microsoft AJAX library, jQuery library as well as DevExpress components and controls. Grid control. DevExpress provides flexible grid with AJAX functionality and ability to create nested grids, e.g. detailed report for selected row of parent grid. This grid has ability to implement “on fly” filtering, when grid header has additional icon which allows to limit number of records based on entered text, selected checkboxes or selected value from combobox which applies to particular column only. Website implemented as C# MVC 3 application for mobile devices. The reason of that project is to provide mostly used reports to the business on the go. Original Reports project with complex grids is not suitable for mobile devices. Common library. Designed and developed .net library written in C# for several projects. Project divided into business layer and data layer. Business layer is implemented as a .NET 3.5 assembly written in C# using Linq2Sql and Linq2Objects technologies. Designed and implemented solution to track changes made by different users from different applications for future troubleshooting. Project PAC. Website for internal usage to provide customer support, sales and finance people ability to manage customers' accounts. Designed and developed from scratch. Project written using C# 3.5, ASP.NET, MVC 2. Website provides web 2.0 experience to load/update data without page refresh. Underlying services for web 2.0 are implemented as WCF services. AjaxToolkit library and jQuery are used too to provide web 2.0 experience. Credit Card Processor. Windows service written in C# uses HTTP GET and POST requests to connect to credit cards merchant provider to process credit card transactions. Website written using C# 3.5 and ASP.NET. Localized to 12 different languages. Localization uses ASP.NET localization tools. My own invention allows translators to translate website directly from webpage. That allows to see context of translating expressions. Once translation is complete the result is available immediately. Website provides web 2.0 experience to load/update data without page refresh. Underlying services for web 2.0 are implemented as WCF services for ASP.NET. AjaxToolkit library and jQuery are used too to provide web 2.0 experience. Website uses wildcard SSL certificate to encrypt data exchange between client's browser and web server. AMC. White Labeling. That project allows resellers to use their domain, own logo and scheme for AMC website. So AMC website will look like reseller's website but not Venali's. To protect customers' sessions reseller's SSL certificate will be applied too.
