I discovered Cristian through his blogging about a very specific security issue I was dealing with on my ad server software, and took him up on his offer of services to address it. I found him to be responsive, professional, quick, and reasonably priced. While it can sometimes seem risky to employ some developer in another country without meeting them, I can recommend Cristian without reservation.

Cristian showed a real commitment when supporting us with our OpenX-problems. Within 48 hours, he was able to not just support us, but solve all issues we had with our OpenX-implementation. I can highly recommend him as a fast and reliable developer.
