Pratyush Kumar Routh

I bring 6 years of backend engineering experience focused on microservices, event-driven design, and cloud-native development. I work hands-on with Java (8/11), Spring Boot, and reactive stacks to build scalable, high-performance services that stay responsive under load.

In my recent roles, I developed asynchronous, non-blocking microservices using Spring WebFlux and Reactive Streams (Project Reactor). I integrated services with AWS (EC2, RDS, S3, CloudWatch) and improved real-time API performance—achieving a 40% reduction in response time for analytics endpoints—while also enabling zero-downtime deployments with Docker and Jenkins CI/CD.

I also built and evolved reactive systems across product, cart, and order domains by designing fully non-blocking REST APIs and Reactor-based workflows. By benchmarking blocking vs. reactive approaches, I improved throughput by 35%, and I containerized services with Docker and deployed to AWS ECS with PostgreSQL. In parallel, I rebuilt synchronous services into reactive microservices and used backpressure-enabled streams to handle large inventory queries, delivering high concurrency for thousands of users.

Earlier, I strengthened backend foundations by migrating monolithic components to microservices, optimizing SQL and API performance, and delivering enterprise-grade features with Spring MVC, Hibernate, and Oracle/MySQL work. I contributed to projects like inventory and energy asset monitoring—reducing API latency by 25% and downtime by 15%—and I continue to deepen my skills through certifications including AWS Certified Developer—Associate and Reactive Java (Project Reactor).
