Über mich
Taking the way of least resistance, by starting implementation before underlying requirements are clear, is a recipe for disaster. I’m making sure that we first speak the same language, before coming up with technical recommendations. My mission is to develop a solution, which can handle your growing needs in terms of workload, changing requirements and team size. Your team will be enabled to maintain the chosen technologies autonomously in the future.
