"Charlie worked as a part-time consultant for us for two years. He is a highly skilled data analyst with decades of experience, and he particularly excels at the most difficult and messy tasks. In particular, he built a system to extract data from a vendor's internal database and create an entire reporting system that the vendor was unable to provide. This system is now an integral part of our workflow. I highly recommend Charlie for any level of work."
