I have 10 years experience as RF engineer. I worked in very small company and multinational corporation but always in multicultural environment (Europe, USA, Japan, India, Korea, China...). I have done R&D work but also customer support for Asian clients. I mainly work in the mobile phones industry but also in the space research domain.
I am now looking for new challenges, preferably in multicultural environment, either in R&D or in customer support in France, Belgium & Switzerland for the moment.
