I'd love to chat. Please reach out to me - not sure the most proper way to do that in an HN thread. I am apinstein on GitHub or check out tourbuzz.net contact page.
I was at php|works Atlanta, but I didn't present. I have presented it at ATLPHP before. I've presented on other topics as well though and usually at least mention that I created phocoa during my bio.
Our position isn't just PHP actually, but that is our primary back-end language. Probably makes the other commenters' posts about multi-language experience all the more relevant. We do a lot of front-end work in Javascript and we use ruby a decent amount as well (rake, chef, capistrano).
