EO cCM is a cloud orchestration platform used to manage and automate network services in a virtualized environment. It provides APIs to create, update, and delete cloud services, and to control virtual resources like virtual machines and virtual applications.

• Worked on backend development for API operations related to cloud service lifecycle management.
• Implemented and enhanced Change VNF Package functionality to support seamless VNF upgrades without service recreation.
• Handled request validation, error handling, and ensured compatibility checks for different service components.
• Worked with MySQL and Hibernate for data persistence and optimized database interactions.
• Debugged production issues using logs and improved system stability and performance.
• Deployed and managed microservices using Docker and Kubernetes.

Interference Layer provides network visualization of coverage KPIs. With the Interference, users will be able to check the signal quality, network quality, and user verified layers for extra authenticity. Interference contains details of RSRP and RSRQ KPI.

• Developed and deployed technical upgrades to improve system functionality and reliability.
• Executed backend server code development for assigned modules, achieving production-grade implementation.
• Collaborated with testing team to identify and resolve bugs, ensuring smooth deployment processes.
• Delivered code-level fixes for production environment bugs to maintain operational stability.
• Mentored junior team members, enhancing their technical skills and project contributions.

Service Gaps is the polygon generated over a smart network coverage layer, which shows the poor coverage zone in the network. Algorithm generates Service Gaps for each band periodically and provides optimization suggestions to improve coverage. It provides the tracking of Service Gaps improvement as well.

• Enhanced functionality of ciris application, resulting in improved user experience.
• Developed RESTful web services for efficient data communication.
• Mentored junior team members, fostering skill development and ensuring timely task completion.
• Analyzing and understanding the requirement and discussing with the team Lead during development planning.
• Used Junit and Mockito to write test cases.
• Provided code-level fixes for bugs raised in production environment, maintaining system stability.
