"Bob is quite possibly the greatest consultant we have used on Upwork. Everyone should hire Bob. The world needs more Bob. In all seriousness, he is an excellent consultant, a wealth of knowledge, and most importantly, an amazing team mate. He is welcome back any time!"

"I would enthusiastically recommend Bob Haffner for any data/cloud engineering projects. Bob has worked with our team to build complex data pipelines, data transformation & analytics scripts, and dashboards. He has been collaborative, communicative, and efficient, working effectively on ad-hoc and complex problems, accommodating changing and incomplete requirements, and enabling our internal team to automate repeatable processes. He is very responsive and transparent about level of effort and turnaround time on projects."
