He hit all targets. Met our expectations. Helped us solve some small issues and corrected all of the eras that where there. Total pleasure to work with and would highly recommend and use him again. [22 October, 2016] Excellent work.. very professional and hits the target. His communication was precise and helped clear up the problems that we where struggling with from the site, making him a great problem solver.
