Technical Lead designing scalable Java backend microservices and event-driven systems for high-performance platforms.
IndiaWhat I'm looking for
I’m a Technical Lead with 10 years of experience designing and developing scalable backend systems using Java, Spring Boot, microservices, Kafka, and AWS. I focus on architecting event-driven distributed systems that are reliable, performant, and cloud-native across banking, healthcare, and e-commerce.
At CODITAS Technologies, I lead a team of 10+ engineers to build RBI-compliant banking systems for high availability and fault tolerance. I drive end-to-end architecture decisions—HLD, LLD, API contracts—and deliver systems that handle 50+ TPS with strong scalability.
My work includes optimizing microservice orchestration to reduce API response latency by 38%, building event-driven solutions for high-volume financial transaction processing, and mentoring junior and mid-level engineers through code reviews and technical guidance. I also use AI-assisted development tools like GitHub Copilot and Cursor to improve engineering productivity and code quality.
Previously, I helped modernize ProClinicX by migrating a monolithic healthcare platform into event-driven microservices, and I built Kafka-based asynchronous workflows using REST APIs and SQS. Earlier, I developed enterprise data validation workflows with Java and Apache Spark, and delivered backend services using Groovy/Grails and Spring MVC for data-driven and platform features.
