$ for guru in {Appeon MVP}: print $guru 

I do believe great software is the result of great teamwork. I do believe spending (lots of free) time in software development must be driven by passion and enthusiasm. Back in 2002 I started experimenting a prototype toolkit following two strong professional attractions: the Powerbuilder language and a development model on the rise, Web apps. This toolkit, Appeon, was about to become my main professional expertise, expanding my horizons to Mobile app development too.

Throughout more than a decade of experience, I've become an Appeon expert, and Appeon MVP in 2017. I had the privilege to meet dozens of knowledgable PB experts worldwide as well as passionate Appeon folks and core developers. I have taught but I have also learned, a lot. Developing high-quality software takes deep attention to details, comprehensive product awareness as well as sound and ever-evolving philosophy: this is Appeon.
