Bertrand PERISSE cherche partenaire tandem français - anglais

I am a french civil servant and a likeable and very correct person, who may work abroad in a few months. My French is excellent and I think I'm able to help you progressing in it. My level in English is between « independant user » (or « upper intermediate », B2) and « proficient user » (a little bit better, C1). I actually need to practise, speaking and writing (preferably with an english mother tongue person). Should the occasion arise, I would be pleased to form (or join) a little group to practise.
