RATNA HARSHITHA MANEPALLI

@ratnaharshithamanepalli

Backend Java developer building secure, high-volume telecom microservices with Spring Boot.

What I'm looking for

I’m looking for a role where I can own backend microservices, design resilient REST APIs, and strengthen security and performance, while working with CI/CD, Kubernetes, and cloud-native deployments with collaborative teams.

I’m a Backend Java Developer with 4.5 years of experience designing and building scalable microservice-based applications. I focus on reliability and performance for high-volume telecom billing workflows, delivering both real-time and batch transaction processing.

I’ve designed RESTful APIs using layered architecture, exception handling, and validation, and I’ve helped reduce transaction latency by 15% while improving system reliability. I also implemented event-driven communication with Kafka to enable asynchronous processing between billing and middleware systems.

Security and modernization are key strengths of mine. I led a migration from cookie-based authentication to Halo OAuth 2.0 for token-based API security, moved legacy deployments to WildFly for modern microservices infrastructure, and mitigated OWASP Top 10 vulnerabilities to achieve 100% compliance.

In cloud-native environments, I’ve supported deployments on Linux servers and collaborated on release management and CI/CD pipelines. I bring a strong foundation in object-oriented design, distributed systems, and performance optimization, including automation via shell scripting.
