Canada - Last active: 3 days ago - Tests: 7 - Portfolio: 6

25+ years of programming, 14+ years as a job. It's not just how I make a living, it's also something I really love and enjoy doing. I develop robust desktop software, great responsive websites, optimize databases and create reports. I communicate well and feel that it is my duty to let the client know how things are progressing. I also give constructive input but respect the client's final decisions. I program desktop programs in C# and VB.Net (both WinForms and WPF) and websites as either ASP.Net, MVC 5 or single page Angular applications. I have worked heavily with MS Access and MS SQL. I have extensive experience writing reports for SQL Server Reporting Services(SSRS) and RDLC reports for web and desktop applications. Here are a few aspects of the challenging projects I have worked on so far. Added eyedropper functionality (pick a color from an image) using HTML5 Canvas and listed fonts installed on the computer to a single page SVG graphic editing web app. Created custom mouse cursor. Runs on Chrome, Firefox, Safari, Opera and Internet Explorer. Created response Bootstrap WebAPI/Angular site to teach Latin. Created an MVC 5 demo website for travel agents to create and manage quotes. Wrote a program to play music on a low-latency and high fidelity 8 output channel professional sound card. Created an output program for industrial displays. Wrote a program that receives industrial protocol messages over TCP/IP and follows with the appropriate action. Read and nicely write INI files. Created solid user registration and product activation for desktop applications. Created graphic editor with easy user interface for complex set of symbols. Advanced document layout for specialized graphics. From a third party website, retrieve the distance between two locations for use in calculations. Load GoogleMaps map in desktop application with route between source and destination addresses. Created an ASP website to edit database. Created custom JqueryUI controls to validate and display the data in a user friendly way. Make websites with HTML5, javascript, and JQuery. Created and optimized MS SQL databases. Displayed time from events in database in the user's time zone. Optimized, rotated and created arrays of 3D data. Created fast working implementation of a query to find areas of similar data throughout millions of records for MS SQL. Made reports (SSRS) with automatic emailing to the clients. Made a RDLC report for a desktop application based on MS SQL. Implemented a full costing program in MSAccess. I also speak, read and write English, French and Spanish fluently.
