Hi there,
Hope you are doing okay.
I understand your project requirement of an e commerce site, with angular 11 and google Firebase as backend. I am really interested in the idea, and would love to work with you on this project.
My Background: I am a freelance developer for web and mobile applications as well as integration of multiple APIs. Currently I am representing as part of Delta Developers. We are an organized association of a group of Tier 1 college graduates and students from India, and have successfully finished around 20 projects, and are in partnership with many firms of India.

Typical E commerce sites will take at least 10 days for building and 2 more days for testing.
