Experience

Metro 2 Format

Delivered a complete back-end application that reads data from Redshift, formats it to metro2, and uploads it to the client's SFTP.

I was the project lead and handled it with the help of three people. I worked on the Airflow DAG, integrating data read, format, and SFTP upload while helping the team complete other significant parts. I wrote Groovy scripts to create Jenkins files, wrote Docker files to create images, and was involved in end-to-end testing.

eCommerce Product

CA product for the operations department reads customer orders and provides suggestions for the people in the warehouses to move goods from one department to another, load trucks, and remove stock from the inventory.

I was the back-end developer who implemented the complete flow. While implementing, I identified that there are no test cases/frameworks integrated with the application. I added the tests and shared knowledge transfer on unit tests to the overall company on how to write tests.

Notification Center

We delivered a complete back-end project to support notifications and emails with attachments.

The notification center was built with Amazon SQS. Every application owner needs to configure their template in the notification center. Applications may use the configured template to send emails/notifications.

Whenever a notification needs to be sent, the application will push a message to SQS with relevant information. Then the notification center will process the message and send an email/notification according to the configuration.
