I am starting with Java based enterprise-oriented solution like EAI/ESB for 3-4 years, and then I shifted my attention to the internet-oriented skills, such as Objective-C and RoR. Last 2 years, I launched a start up, and have been predominantly working with the development of websites and iOS applications for both outsourcing and my own products.
I am a continuous learner, willing invests time in core skills or tries a variety of techniques. Meanwhile this approach can usually help me to pick up new skills quickly and succeed on challenging projects.
