It was ~2.5 years of great people, challenges and success. But at the end of the day (er.. 2.5 years), I needed a change. It didn't took long (actually 5 days) to get a good & concrete offer in a different environment.
So far I don't regret my decision and knowing me, I don't think I'll ever regret it. Now I have new people to meet, new challenges to overcome, and more successes to achieve!
