Build Shopify App
For Customer support desk.
Ticket Management App.
Played with almost all API of shopify.

We were working on Event-based-architecture. The input to the
AWS-Lambda is the Json object (event like view page, added items to cart, ordered
product, etc) the general events which customers do on e-commerce sites.
The output was to save the data in the database as per the schema.
Step 1: Validate the data’s correctness, and completeness.
Step 2: Transform the data into required format.
Step 3: Build the cypher/query to inrest the valid data.
Step 4: Insert the data into database, and retry if error occurs like resourse not available.

The input to the AWS-Lambda is the Json object which includes a person
id.
The output is to calculate the customer all properties and save the data in the
postgresql database.
