Senior Java backend full stack engineer specializing in scalable microservices, reactive APIs, and cloud-native systems.
IndiaWhat I'm looking for
I am a Senior Java Backend Engineer with 9+ years building microservices, event-driven systems, and reactive APIs using Java (11–21) and Spring Boot. I drive monolith-to-microservices transformations and deliver high-throughput, resilient systems across AWS and GCP.
My hands-on work includes designing reactive WebFlux APIs, Kafka-based event pipelines, serverless functions, and containerized deployments on EKS/GKE. I optimize CI/CD pipelines, implement observability with Prometheus/Grafana/CloudWatch, and automate infrastructure with Terraform and CloudFormation.
I also contribute to full-stack delivery using React and Angular when needed, focusing on performance, maintainability, and scalable architecture that reduces costs and improves deployment velocity.
