Although my professional career has been mostly about system and application programming in C, C++ and Java, I never hesitated to discover new things, and got familiar with modern web technologies on both, server and client side.
One of my current projects utilizes Python with Flask framework at server side and HTML5 (plus jQuery and Bootstrap) at client side. The project is a web-based media console for controlling multiple-zone home audio system built on top of Media Player Daemon (MPD) and Raspberry Pie computers.
Also, once in a while I do BlackBerry apps. You can find my “portfolio” here. If you need a BlackBerry app I can do it for you. Contact me and we’ll discuss the details.
