Senior Java Full Stack Developer specializing in cloud-native, reactive microservices and modern React frontends.
IndiaWhat I'm looking for
I am a Senior Java Full Stack Developer with over 9 years of experience building reactive, event-driven microservices and scalable cloud-native systems on AWS and GCP. I focus on delivering high-throughput, resilient architectures using Java, Spring Boot, WebFlux and Kafka.
On the frontend I modernize React applications (React 18/19, Hooks, RSC, Redux Toolkit, Suspense) to improve performance and user experience, having achieved measurable frontend performance gains.
I automate and accelerate releases through CI/CD (Jenkins, GitHub Actions), and improve observability with Prometheus, Grafana, Zipkin, and CloudWatch while reducing costs via serverless migrations to AWS Lambda.
I operate as a builder, optimizer and scaler during monolith-to-microservices transformations and high-throughput system builds, available to join within 30 days and open to relocation and visa sponsorship.
