Backend engineer building high-scale Java microservices with Kafka and Redis.
IndiaWhat I'm looking for
I build distributed microservices in Java and Spring Boot, and I’ve worked with IBM for Mercedes Benz at global warehouse scale—handling 10K+ transactions per day with high availability and fault tolerance.
I design event-driven pipelines with Apache Kafka and focus on low-latency APIs by optimizing caching (Redis/in-memory) and database queries through indexing and batching.
Earlier at Infosys for Apple and Finacle, I worked on a high-throughput financial payment system, implemented the Saga pattern for distributed transactions, and improved processing efficiency and API performance through query optimization and service design.
