Nezha has over 12 years of experience in audiovisual production and since 1996 has produced over 50 documentary films (series and single productions) from which many has won awards in French and foreign film festivals.

After 5 years spent managing LES FILMS GRAIN DE SABLE production company, producing films of Jean Michel Carré and other directors, she decided to create TACT Production (the acronym in French stands for Télévision Audiovisuel Cinéma pour Tous).

The creation of TACT Production in 2001 stems from the desire to produce quality documentary and fiction films in France and abroad. Films which translate the world in which we live, which recount, express and explore our societies, in all their complex diversity.

Nezha is a regular consultant for AIBD (Asia-pacific Institute for Broadcasting Development) as a teacher in "Cultural & Educational TV Documentary programs" and she is also a teacher in Audiovisual Production managing at "Marne La Vallée" University.

In 2004 , she was a jury member of the 1st International Women Film Festival of Salé (with Nargiss Nejjar as President). In 2007, she was a documentary jury member of the 13rd International Mediteranean Film Festival of Tetuan.

In 2007, TACT Production Morocco is born with the aim to be part of a South-North dialogue, setting up coproductions between Morocco and France as well as with other Southern countries and European ones, and with countries from Latin America.
