About
I’m Prashanth Chintala, a Senior Software Engineer specializing in Core Java and Spring Boot to build scalable, high-performance, event-driven backend systems. I focus on concurrency and distributed systems—leveraging Kafka, Redis, resilient patterns like retries, DLQ handling, circuit breakers, and the Saga pattern—to deliver reliable services under high workloads.
In my roles, I design secure APIs and authentication with OAuth2/JWT and RBAC, optimize database queries and caching for latency and throughput, and use Java 21 features (including Virtual Threads) to improve performance. I also bring production-ready engineering habits through automated testing (JUnit/Mockito/JMeter), observability with logging/tracing (ELK and OpenTelemetry), and CI/CD and deployments using Docker, Kubernetes, Jenkins, and ArgoCD.

Work experience· 4 roles
Developed and supported a cloud-based, high-volume workflow platform using an event-driven architecture. Built a resilient Kafka-based scheduling pipeline using the Saga pattern for distributed transaction state management (bookings, cancellations, and real-time hospital system sync). Led scalable interoperability integrations with EHR systems (Epic, Cerner, Meditech) using Apache Camel (Java DSL) and HAPI HL7v2 ADT/ORM message ingestion, validation, and parsing. Implemented secure stateless authentication with OAuth2/JWT and RBAC to isolate patient data access. Improved concurrency and performance using Java 21 virtual threads, CompletableFuture, and thread-safe processing, reducing P99 API latency for calendar availability lookups. Added robustness with Kafka DLQ/retry handling, manual offset commits, Resilience4j circuit breakers, idempotency patterns, and tuned timeouts/backoff for outbound calls. Enhanced monitoring with ELK and OpenTelemetry for faster production troubleshooting.
Designed and maintained scalable Java/Spring Boot microservices for high-volume concurrent requests and business workflows. Built RESTful APIs and event-driven microservices with Apache Kafka to enable asynchronous communication across distributed services. Applied Java concurrency patterns (ExecutorService, thread pools) and thread-safety practices to improve throughput. Implemented persistence and data access with Spring Data JPA and Hibernate, optimizing queries with indexing and query tuning. Owned performance testing using JMeter and JUnit to identify bottlenecks across APIs and databases, improving reliability and response time under concurrency. Investigated and resolved production issues using logs, monitoring, and database analysis. Supported frontend integration by building reusable Angular components/services and connecting them to Spring Boot APIs. Delivered containerized deployments via Docker and Kubernetes through Jenkins-based CI/CD pipelines, including Agile collaborat
Developed backend services using Java and Spring Boot, improving processing efficiency with optimized business logic using Streams and lambda expressions. Built and maintained RESTful payment APIs with JSON schema validation for reliable transaction exchange. Implemented Kafka-based payment event streaming for real-time publishing and consumption of transaction events. Used JMeter testing to identify and resolve processing and database bottlenecks, improving performance under concurrent transaction loads. Built responsive React.js applications using reusable components and integrated RESTful and third-party APIs. Collaborated with UI/UX designers, backend engineers, and QA teams throughout development, testing, debugging, and production delivery.
