Hello,
I'm a PrestaShop Certified Developer with 5 years experience in PrestaShop and 7 years in programming.
I created over 40 PrestaShop stores from scratch. Recently I developed 5 modules for my own which was verified and accepted on Addons by PrestaShop Team itself which is something :).
I never found a problem with no solution by my side, so I consider myself a professionist.
For any question, don't hesitate to contact me.
Thank you.
