At Mahindra Comviva, I lead an 8-member engineering team delivering backend platforms for Airtel India, StarHub, Indosat, and Orange. I build Java-based distributed systems and REST APIs for telecom CRM and number management products serving hundreds of millions of subscribers.
I've helped migrate six telecom hubs to active-active microservices with 99.9% uptime and zero-downtime deployments. Using Spring Boot, Quarkus, AWS, Kubernetes, Redis, Aerospike, Kafka, and Oracle, I've reduced API latency by 40%, improved event throughput 3x, and optimized queries on 3.4B+ records from 12 seconds to under 800 milliseconds.
