Scrum Master, and agile practitioner. I have taken a company from waterfall to agile, worked as Product Owner, Scrum and Team Member. I am also familiar with eXtreme Programming and best-practices for software development.
I have had the opportunity to transition a company from waterfall to agile development using Scrum, and eXtreme Programming. From overcoming resistance from management, and developers to retrospecting into more effective working conditions, I have had a chance to do it all.
During that time, we saw productive and profits rise, while developer and customer satisfaction went through the roof.
