  • image of Daniel1344 Project for Oleksandr P. $17.00 USD

    “Oleksandr P. Was exceptional, the man understands a wide variety of materials to get any job done it seems. Given a task he works to research the various concepts and how they mattered within a project as within the programming tool MathCad in order to complete it. Given his efficiency with work, no doubt he knows his stuff. It falls more on the project founder to be more punctual & giving right info while Oleksandr does what he does.”
