Global SIP Trunking Call Service Application: 

• Developed call service applications in the telecom domain using Java, JAINSLEE framework, and SIP protocol to deliver project-specific software solutions.
• Independently designed and implemented core modules of the application.
• Created REST APIs for data provisioning with Spring Boot.
• Implemented various design patterns to enhance code modularity, maintainability, and scalability in the project.
• Utilized Hibernate for Object-Relational Mapping (ORM) to improve data persistence and streamline database interactions.
• Conducted unit testing with Junit, Mockito, and Wire mock, and performed functional testing of the application and its features.
• Built applications using Maven and deployed applications using Ansible.
• Enhanced database performance by optimizing queries, implementing indexing, and tuning queries, resulting in significantly faster load times.
• Proficient in version control with Git, including committing code changes, merging branches, and collaborating using Git workflows.
• Applied Agile methodologies (Scrum) to promote collaboration, adaptability, and iterative development processes.

Performance Test Analyzer:  

• Designed and developed a performance test analyser tool for telecom applications.
• Used the Spring Boot framework, leveraging its powerful features to create a scalable, maintainable, and efficient solution.
• Integrated Hibernate ORM with the Spring Boot application to manage database interactions efficiently.
• Simulated calls to the telecom application using SIPP for performance testing.
• Created graphs with shell scripts to evaluate performance across different metrics and enhance overall efficiency.

Call Admission Control Service:

• Built the service using Spring Boot microservices architecture, with service registration and discovery handled through Eureka Server.
• Implemented Redis Pub/Sub for real-time communication between calling applications and the CAC service.
• Developed logic to evaluate incoming/outgoing call requests against dynamic thresholds (bandwidth, call limits) fetched from Redis and/or the database.
• Enabled inter-service communication using Spring WebClient with fallback mechanisms using Resilience4j Circuit Breaker for fault tolerance.
• Returned real-time responses to determine whether a call should be accepted or rejected based on trunk capacity.

• Xcelerate Warrior Award by TCS.
• Received client appreciation for successfully developing and implementing major features, demonstrating exceptional technical skills and commitment to project success.
