I used to be an IBM programmer, then a computer network manager, and latterly taught computing (Word, Excel, etc) before the systems software side became far too complicated for me!
So with that background I can really appreciate David’s knowledge and skills, and I particularly take to his reasonable fees, that he works quickly but doesn’t rush, is friendly and open so will listen to you and your difficulties. He doesn’t blind you with jargon, will explain what he’s doing and why, or just fix it if you prefer.
He’s got me out of trouble when the problem was beyond me. I’ve recommended him to many friends and colleagues.
