I built so many ecommerce website which has complex and large logic. It includes Marketplace website, a small store to large store and etc. Also I worked on backoffice project such as integrate with Hubspot, Netsuite, QuickBookt and etc. while working with them I used their own script such Suitescript, HS-script... With my skills, experience and attitudes, I believe that I can bring a success to your job. Looking forward to your reply. Regards,
