Experience

Huali eCommerce website (Development)
One of the largest eCommerce flower sites for which I was in charge of the design and development. The front-end is developed under a mobile-first strategy. The back-end is developed to be modular through an order processing priority system.
Biggest Food Ordering site (Development)
