Jason Cline is a Technical Advisor at Celestial Systems Inc.. Colleagues describe them as "It has been a true pleasure and honor working with Jason. His extensive knowledge of front-end Web technologies ranges from the early days of JavaScript frameworks through to the very newest developments. Jason is an avid learner and does not hesitate to jump in and immerse himself in whatever technology he meets. He can then take this "overnight mastery" and apply it to his code, or to architecting new applications or even to step back and mentor a team of developers through the entire software development life-cycle. In short, Jason is a brilliant engineer, a talented software architect and a solid engineering manager. I learned a great deal working with Jason at Sencha and I sincerely hope to have a chance to work with him again in the future! Highly recommended!" and "Jason joined Sencha as a member of our fledgling services group. He leveraged his experience in mobile to quickly become a subject matter expert for Sencha and all things mobile. He was a key member in our ATT relationship and drove our deliverable to the next level."
