Pramod Sadalage is director at ThoughtWorks where he enjoys the rare role of bridging the divide between database professionals and application developers. He is usually sent in to clients with particularly challenging data needs, which require new technologies and techniques. In the early 00's he developed techniques to allow relational databases to be designed in an evolutionary manner based on version-controlled schema migrations. He is the co-author of Refactoring Databases, co-author of NoSQL Distilled and continues to speak and write about the insights he and his clients learn.
