Message

At HEMNETTE WEB SOLUTION (PVT) LTD, I led the migration of Telstra Order Express from a J2EE monolith to a Spring Boot microservices architecture. I also led integration of backend microservices with the Angular frontend.

On the Telstra DES portal, I worked on backend services in Spring Boot and the Angular frontend for device enrolment workflows spanning manufacturer platforms. I’ve also guided teams in maintaining Azure cloud services, WSO2 Identity Server, and WSO2 API Manager.

Earlier, I worked with teams to develop a pet tracker and a J2EE application for a mobile service provider. At VISNI (PVT) LTD, I designed and developed backend REST APIs for mobile apps using Spring Boot and MySQL.
