Most of my past experience is in Enterprise Java and related technologies. I started working with Java in 1996, prior to that I did about 5 years of C/C++
My last 8 years are all contract jobs for large clients, all loosely related to Spring framework and other various Open Source frameworks. Since 2008 I've been closely involved with Android development, authoring and writing Jobrio (a.k.a. Hire-A-Droid) and Droidin. I'm also collaborating with good folks of Flud reader to deliver Android version of their popular app I also (occasionally) maintain my dev blog
