    ⭐⭐⭐⭐⭐"I hired Shafir to repair a corrupted SQL database. We used 2 other SQL engineers prior to meeting Shafir and also attempted a repair using a database repair application which also failed. We were at a point where nothing was working and we were coming to the conclusion that this was not repairable as there were too many errors. Shafir was very confident that he could repair the database and after watching him work for just a few minutes I immediately felt some hope of a successful repair. After working on the database for several hours Shafir managed to repair the database and get it working better than it was before. Working 20 years in IT I had never seen anything like it.
