En résumé

During my 8 years’ experience with SFR I have developed a high strong technical experience in the domain of Voice Core Network as well as project managing. I also have improved my organizational skills and my analytical approach to problem solving with strong planning.
I’m particularly interested to join an international work environment and I’m open to work worldwide.
