I joined ThoughtWorks because I believe in the company's vision of a humane corporation, dedicated to doing the best business possible while also effecting social change by having people committed to using technology as a way to impact the world.
At ThoughtWorks, I'm mostly a developer so I get to code a lot of the time but also help with sales pursuits, mentoring and business development -- not bad for someone who would be expected to be completely post-technical after 15 years in IT. I also serve on ThoughtWorks Technology Advisory Board, which is all about our global technology strategy but really means I get to give my probably not so humble opinion on various technology-related subjects to the rest of the business.
Ronaldo wanted to be a science-fiction writer, but ended up working with computers because he had to agree with Alan Kay who said that "the best way to predict the future is to invent it". In the 15 years he's been working in IT, he's been helping his clients to do just that--to realize their visions of the future by coming up with better ways of applying technology to their businesses. He doesn't believe in silver bullets, but is convinced that technology is one of the key factors to bring about social change in the world. He still writes some science-fiction and considers his kids his best tale.
