Matt is a technical product manager at Pivotal. He is a 15 year veteran of the enterprise IT industry, with experience spanning numerous business domains. He is the author of recently published Migrating to Cloud-Native Application Architectures from O’Reilly, available as a free e-book download.

Matt is obsessed with the idea that enterprise IT “doesn’t have to suck”, and spends much of his time thinking about lean/agile software development methodologies, DevOps, architectural principles/patterns/practices, and programming paradigms, in an attempt to find the perfect storm of techniques that will allow corporate IT departments to not only function like startup companies, but also create software that delights users while maintaining a high degree of conceptual integrity. His current focus is driving Pivotal’s solutions around supporting microservices architectures with Cloud Foundry and Spring.

Matt has spoken at conferences ranging from JavaOne to OSCON to YOW!, is a five-year member of the No Fluff Just Stuff tour, and serves as Technical Editor of NFJS the Magazine. Matt is also the founder and past president of the Memphis Java User Group.

Gil Tayar


From the olden days of DOS, to the stratospheric architectures of Wix, Gil was, is, and always will be, a software developer. Currently a software architect at Wix, he has in the past co-founded WebCollage, survived the bubble collapse of 2000, and worked on various big cloudy projects. He still doesn’t know whether static languages or dynamic languages are the best.

I have given the following talks:

YGLF 2015 - Old Gods & New: A Vision of Backend & Frontend (sorry, bad sound)

JSIL 2015 - From Callback Hell to Async Heaven - Promises

JSIL 2015 - Navigating the wild seas of ES6 modules (Hebrew)

My talks, while highly technical, tend to have a certain humorous (and literary) structure to them, as I try to make the sometimes dry material come alive.
