Anyone can throw a Sencha ExtJS or SenchaTouch app together and make it work. Building tooling around the process is an entirely different story. Having been through tens of releases of SA, I can, through my own personal experience, assure you that understanding what and why the Sencha Architect generates the code it does is worth hearing about.
The guys who you will meet and will be presenting at this meetup are the guys that built this awesome and successful product (and continuing to improve it release after release).
Topics we will be talking about include what is the best architecture when building a scalable sencha app, what tricks do they use in the tool itself that you should be using. Of course, lots of new features will be demonstrated and as always, the best part is the Q&A so bring any and all your Sencha questions. We will have plenty of time to ask questions as a group as well as the normal meet and greet.
Hope to see you there!
