“What can I say? Leo was fantastic! I asked him to take over updating an app written by another programmer. Leo more than met my expectations, he updated and improved the function of my game "Gumball Words" immeasurably. It is now a much smaller file and a much more responsive game.Additionally, we had many problems with uploading to the app store because of certificates, keys, provisioning files, etc all previously managed by someone else. Leo took the extra time, without complaint and got it uploaded. I will absolutely use him again!”
