Profile

I am a professional, competent and experienced software engineer, specialized in Ruby on Rails and web applications. Over the years I have developed complex projects from start to finish, and have a good working knowledge of a software product's lifecycle and programming methodologies. Agile programming techniques are not new to me either. I am an open and social person with good communication skills, and know how to motivate a team and deliver high quality products.
