Hi,
Currently we are working on e-commerce app, which includes features like,
shopping cart,
payment gateway integrations,
order management systems (OMS),
without sign in cart management and merge cart after sign in,
product listing and details,
order summery management and cancelations,
Promo code and coupon code apply on cart products, etc.
We have pretty decent experience in e-commerce app so i think i can understand and contribute more to your application.
Looking forward to work with you,
Thank you.
