    Andrew was great at this project. With very little instruction, he was able to pick up what we were doing and contribute right away. I would definitely recommend him to anybody looking for any Python and SQL expert.

    Andrew is the man! I was manually doing a task that took 1-2 hours per day. It was a data entry nightmare and made me hate my life. In 2 days Andrew programmed up a simple python script to automate the process. Now what took 1 hour takes 1 minute. What would take all day can be handled in 2 minutes. Andrew is amazing to work with. Truly a professional and knows his way around programming. He completed this job before the deadline, was very upfront and communicated well, and most importantly, the script worked the first time. No debugging or pulling out my hair. Just working code. Thanks a ton Andrew :)
