  • hình của jackiemaina22 STM 32 Firmware $774.00 CAD

    “Be careful and dont use this freelancer, he will lead you along make sure that he has structured the milestones in a way you pay him and get no work for it. I am currently working with freelancer company to get my $770 because the code he offered is useless and he did not complete the work and just went off without even as much as a word or apologies. He heft me waiting and sending a message day after day without response. I believe the other reviews are fake. there is no way he has the work ethics or the expertise to do the job, any job. Please save your money. I am still trying to recover mine.”
