L’over-engineering ? Pas son truc, elle préfère se concentrer pour avoir un run solide, des outils de déboggage efficaces et un code sympa à relire.Pour elle, développer sans effort ça passe aussi par livrer sans trembler : feature toggles, configs dynamiques et plus encore, elle est là pour partager ses techniques.Elle est aussi convaincue que, pour passer de bonnes journées, il est important de partager ses idées avec ses pairs ; c’est pour cela qu’elle aime prendre la parole et partager ses expériences.
