Software Engineer at Ciklum

December 1, 2024 - Present

Architected backend Java 17 services and RESTful APIs using Spring Boot, Hibernate, and PostgreSQL in a layered controller-service-repository architecture for a high-traffic platform processing millions of records daily. Decomposed monolithic modules into modular Spring Boot microservices with SOLID principles and domain-driven boundaries to enable independent scaling and deployments. Optimized a multi-level referral logic engine by tuning SQL joins, adding composite indexes, and refining Hibernate execution plans and fetch strategies, improving data-processing efficiency by ~45%. Built asynchronous REST endpoints using Spring @Async and CompletableFuture with resilience patterns (retry/timeout/circuit breaker) for long-running payloads. Secured APIs using Spring Security, OAuth2, and JWT role-based authorization and validated business logic with JUnit and Mockito tests following TDD. Collaborated with product owners and QA during Agile/Scrum ceremonies, including sprint planning, back

Java Backend Developer at Nagarro

July 1, 2022 - April 1, 2023

Developed Java Spring Boot backend services and microservices integrated with PostgreSQL and MongoDB using Spring Data JPA to support a data-integration platform for multiple downstream consumer systems. Built Apache Kafka producer/consumer pipelines for real-time metadata synchronization with topic/partition and consumer group configuration for decoupled, fault-tolerant event-driven delivery. Deployed and maintained containerized services on Linux using Docker, Apache Tomcat, and Kubernetes (GKE/AKS), managing pods and rolling deployments for high availability and zero-downtime releases. Implemented CI/CD pipelines with Jenkins, Bitbucket, and Jira for automated Maven builds, unit tests, static analysis, and artifact deployments. Created documented versioned REST APIs with OpenAPI/Swagger and integrated Redis caching with TTL eviction policies to reduce latency and database load.

Java Developer at Techrover Solution

January 1, 2021 - June 1, 2022

Developed core Java components, RESTful API integrations, and Spring Boot/Hibernate service-layer business logic for high-volume financial transaction processing across integrated enterprise platforms. Improved production stability to 99.9% uptime through monitoring, log analysis, and root-cause debugging on Linux-hosted instances. Tuned SQL via indexing, query tuning, and stored procedure optimization; applied Hibernate caching and batching strategies to accelerate data retrieval from high-volume transaction tables. Authored JUnit/Mockito unit and integration tests with mocking/stubbing to validate complex business logic and reduce regressions. Managed builds and dependencies with Maven using Git/Bitbucket and enforced branching and PR review practices for consistent, conflict-free production deployments.
