Let's make a difference

I'm a products guy with all the skills you need to build great web applications and an eagerness to constantly learn and improve.

Can you afford to build a product no one likes to use?

I'm always looking for new challenges in business as well as web technology so if you have a nice idea and need someone who knows how to execute it well, then I am the right guy!
