Last Tuesday I presented my work on the developers at Simplon.co, at Montreuil, Paris. Simplon.co is a network of schools proposing free of charge training to become developer of Web sites, mobile applications and other digital devices. These trainings are addressed mainly to unemployed people (young people under 25 years old, with little or no educational background, coming from working class suburbs or rural regions, old people and people in handicap situations) with a goal of a parity between men and women.
