Tabby 2 - Kids Audio Player

Due to the absense of quality, parental-controlled audio player apps for children aged 1+ we simply created one with all the features needed to introduce children to the world of music and audiobooks. Getting into native Android Development (Java) was in line with my general skill development plans = Win! Building apps is a lot of fun and introduced me into lots of new concepts. We have great plans for Tabby and its feature set will grow over time.

Proactively, I approached the founder of Musicone.fm, with a re-design idea (mockup) for his amazing Online Radio Station. He immediately fell in love with its direction and approved the implementation of the design alongside a complete content migration from the old site. From that point on, I was in charge of designing and coding the entire site making sure all of his previous content migrated correctly.

1-Level Amiga PANG prototype

Weekend Hack-a-tron! During a longer weekend session I wrapped my head around Corona SDK with the goal to create a simplified, 1-level version one of my favorite Amiga game called "Pang".

The game shows most of the core Mobile Gaming concepts in action: Character movement (sprites), touch controls, physics, menu (layer) management, simple calculations, sound.

Voice Recognition Program

In 2009, I worked on a small Windows application that helped me control my 5-man team of World of Warcraft characters when I looked into the arts of multi-boxing (playing 2+ characters at the same time). Boss encounters and heroic instances enforced the use of most of the classes' synergetic abilities' which increasingly complicated the controls & configuration. Being able to simply say what I wanted characters to do felt like a big win and helped me focus on the fight essentials e.g. healing/tanking while at the same time simplified controls. The most challenging part was getting cross-windows/process communication right i.e. when sending keystrokes to other programs.
