I'm a software developer living in Brazil very passionate about PHP and test-driven development. Besides doing freelance on the side, right now I'm building a SaaS app, and you can keep track of it by following me on twitter.
I've worked in several industries including newspapers, telecommunications, ticketing (think Eventbrite) and internal softwares for big companies. If you want to hire me, shoot me an e-mail!
Besides working for me and others, I also record screencasts, mainly about test-driven develoment, and deliver them for free on my Youtube Channel. You can check them here.
