What I'm looking for

I'm seeking a Java Backend Developer role building scalable backend applications with Java, Spring Boot, Hibernate, and Quarkus.

At iFour Technolab Pvt Ltd, I developed backend applications using Java, Spring Boot, Hibernate, and Quarkus. I also built RESTful APIs and GraphQL services for frontend integrations and transactional workflows.

For Casino World, I worked on backend systems, customized Keycloak IAM, and integrated third-party gaming platforms. I also applied caching techniques and tools for responsible gaming.

On Terminal Bet, I developed wallet rollback, ticket reset, and reporting APIs. I integrated printer apps and used optimistic concurrency control to address race conditions in wallet transactions.

I designed the backend for PolyRepo Analyser, creating GraphQL queries and REST APIs to retrieve GitHub data. The project also included repository issue tracking, trend visualizations, label handling, and filtering.
