Working with Andri was a professional experience. His expertise in handling data allowed him to identify the root issue within the code, going beyond a mere figure legend problem to address issues within the R code processing the data itself. Communication was clear, and our video chat enhanced the efficiency of our collaboration. I would consider hiring Andri again for similar tasks in the future.
