Developer for Shopify App Store Needed

I would would like to build a Shopify app with the following features:

- Automation Flow Page
- Welcome Flow Page
- Browse Abandonment Flow
- Shipping Notifications


Please note, I am only looking for Shopify App developer. And the app goes here https://apps.shopify.com/


I am a bit new to this but I know exactly what I want and what my budget is.


Based on the requirements above,

Tell me,
How soon you are available
How you work, as individual or you have a team
How long it would take to implement these features from scratch
Which tools stack/language(s) will you use?


Kindly provide answers to these in your bid. Also, do not apply if you’re not a Shopify store app developer.
