India

Message

At Infosys, I delivered 8 production microservices using Java 17 and Spring Boot 3, integrating Kafka messaging and REST services. I tuned APIs handling 10,000+ concurrent requests, reducing average latency by 25% with Redis caching, asynchronous patterns, and query tuning.

At Amdocs, I built and maintained 10+ Spring Boot microservices for telecom systems and refactored APIs from a legacy monolith, reducing average response time from 1.2 seconds to 800 milliseconds. Earlier at Cognizant, I developed Java backend modules and resolved production incidents through root-cause analysis and ELK Stack monitoring.
