More on the project:
A world leading video-sharing platform, sporting 300+ million unique visitors and 3 billion video views worldwide each month, has partnered up with Pentalog for the purpose of continuing their growth.

Our client is searching for a C++ Developer who can help with the company’ goal: offer the best content collected from users, independent content creators and premium partners.
