The North Face

An eCommerce project based on MuleSoft as an integrating platform. I was the team's senior developer and we worked on creating new system layer APIs and integrating them with the existing Process layer APIs. In the project, I led two more developers. As part of our day-to-day, we also worked on fixing critical bugs.

Air Canada Enterprise Information Portal (EIP)

In the Air Canada project, I worked in the shopping POD of the EIP, an enterprise-level application. As part of this team, I got a chance to work on DWL, Mule 3.9 and 4.0, ObjectStore, AWS DynamoDB, and MUnit. Also, I was lucky to be able to wear many hats like developer, TBA, and solution architect. It was a great learning experience for me.

Edward Jones

I also performed some architect roles like setting up the proxy servers, creating and using Keystore and Truststore certificates, creating alerts, setting up functional monitoring and developing custom policy, and applying them on the APIs in Anypoint Manager.
