Project for MikeRRR €150.00 EUR
“Mike is a truly great guy who really knows what he`s doing. Even the task (server down with no reaction) was really tricky and he didn`t know the server he solved it and got it up running within a extremely short period of time. We will award him any further projects with complete trust. Thank you for the excellent work!”
