Paul deGrandis (@ohpauleez) and Kevin Lynagh (@lynaghk) are two anchors of the Clojure community, perhaps especially of the ClojureScript wing. Both Portlanders, they’ve been elbow-deep in core.logic and a ton of ClojureScript tools and libraries like shoreleave, cljx, c2, and more. They’ve stormed the Clojure world in the past year or two, going from zero to taking up residence in #clojure to speaking about Clojure and ClojureScript everywhere.
Kevin is the founder of Keming Labs, which specializes in “building data-driven UIs”; Paul has worked at all sorts of places like Etsy, Comcast, and TutorSpree.
Enjoy!
