Project Overview
Built a microservice-driven backend system to manage toll-free number provisioning for telecom clients. This included automating number allocation, managing geographic routing, and syncing with client onboarding systems via REST APIs.
Challenge
The core challenge was refactoring monolithic Java EE components into microservices without disrupting production environments. Coordinating deployments across staging and production using CI/CD pipelines while maintaining API stability under concurrent sessions posed complexity. Ensuring test coverage and rollback safety during iterative development added to the delivery challenge.
Results
Reduced deployment-related errors by 40% through containerized microservices and Jenkins-integrated unit testing. Increased release velocity with automated builds and improved rollback strategies. Delivered a robust provisioning engine that significantly cut onboarding time for new telecom clients and enhanced operational traceability using detailed logs and endpoint documentation.
