Stefano Sega Head of Software Engineering at Virgin Mobile

Ivan is a great System Manager and I had the pleasure to work with him. He has a great experience in the Telecommunications industry and excellent problem solving skills, allowing him to quickly analyze and solve any issue on complex systems and tech platforms. His knowledge of telco business together with his wide tech skills helped the company greatly in handling IT operations and production support. On top of this, he's an amazing colleague and had a great time with him in my team.
