« Mamadou est venu nous aider à réorganiser notre panneau d’arrêt via un outil de rapport, Crystal Reports. Mamadou a réussi avec succès le travail de précision, au pixel près, puisque nous voulions un rapport similaire au design graphique original. Il nous a aidés à découper le projet par cycle et à intégrer le rapport à notre logiciel corporatif. La qualité que nous avons appréciée était le souci du détail et la constance. Mamadou a été très professionnel et connaît plusieurs autres technologies. Merci. »
