I’m a Java Backend Developer with 6+ years of experience designing, developing, and testing responsive web applications and microservices using Spring Boot and Spring Cloud. I focus on clean architecture, reliable integration, and performance across the full SDLC.

In my current role as a Sr Java Backend Developer at Morgan Stanley, I build RESTful services and event-driven systems, including Kafka pub-sub architectures and real-time search integrations with Elasticsearch. I also secure endpoints using Spring Security, JWT/OAuth-based approaches, and document APIs with Swagger while validating functionality with tools like Postman.

Previously at Roche Canada, I delivered backend and integration work across Spring MVC/Spring Boot, SOAP services (JAX-WS), GraphQL APIs, and persistence with Hibernate/JPA over PostgreSQL. I’ve also worked with messaging (RabbitMQ), caching with in-memory stores like Redis, and cloud automation using AWS/Azure services, Docker, Kubernetes, and Terraform.

I bring a strong engineering mindset—test-driven development with JUnit/Mockito, CI/CD automation with Jenkins/Azure DevOps, and disciplined collaboration in Agile (Scrum/Kanban). I’m energized by scalable platforms where I can combine Java expertise, secure API development, and modern cloud-native delivery.
