    IMS Integration Professional

    Egypt - Tests: 3 - Portfolio: 3

    In an evolving IT & telecom world where convergence is the key point into bringing more content rich services with cheaper prices I had so far profound experience which is a mix from both worlds. Working with IMS & NGN technologies made me come across new evolving protocols such as SIP. I consider myself to be lucky combining best from both worlds together with the ability to troubleshoot large scale telecom & IP networks. I don’t like to have a stagnant assignment and try to find a motivation even on a normal low-profile working day, the team can always find something to fine-tune; monitor anomalies before being discovered. I try to evolve and enhance my technical knowledge, most of the courses i had were self-financed. I consider myself proactive. I always like to motivate my colleagues, I prefer to follow the ‘giver’ model as suggested by Adam GRANT. Constructing team share-point and conducting regular knowledge transfer sessions always keeps the team motivated and aware of lessons learnt.
