I am maintainer of concrete5 blog app, one of the leading 3rd party concrete5 addons, I contributed wordpress import->concrete5 app code, i've made core contributions to concrete5 and i've written tons of stuff for clients. I have singlehandedly eliminated the need for wordpress on concrete5 sites for some pretty large sites.
I'm also writing a book on concrete5 application development.
