"If you want it done - but done for good - have Răzvan own it. I witnessed first hand Răzvan's ability to navigate uncertainty, pick up a new skill or research which technology/pattern fits the task best - always leaving a trail of documents motivating his decisions & sharing context. When dealing with complexity, Răzvan is a first principled thinker with an unrelenting will to untangle the problem and see it done to completion. Răzvan has an impeccable work ethic, deep engineering & software architecture skills and a diverse breadth of experiences to back his straightforward opinions. I strongly recommend Răzvan as a staff engineer."
