Khalid is undoubtedly a Drupal master -- besides using several of the modules he developed on my site, he has also shown an incredible ability to diagnose and solve problems.
When I contacted Khalid a week ago my site was in crisis mode. Load times were slow, traffic was down and nobody I contacted had been able to pinpoint the problem. Everyone knew MySQL queries were overloading the server, but nobody knew why or how to fix it.
After several days of diligent work and diagnosis, Khalid was able to not only tell me what specific queries were causing the load, but also propose and implement a solution.
In the future, I will always turn to Khalid first for performance optimization and database tuning.
