At Siemens, I build real-time systems for railway information management and adaptive road traffic control. I develop Java Spring Boot microservices that support live operational workflows.

For Smart Asset Suite, I designed bidirectional WebSocket APIs for locomotive remote start and stop operations, securing more than 50 REST endpoints with Spring Security, JWT, and OAuth2. I also improved Spring Boot microservice response times by approximately 30% through Apache Camel route optimization and stronger exception handling.

I build fault-tolerant, event-driven services using Java 21 Virtual Threads, Resilience4j, Kafka, Protobuf, GraphQL, PostgreSQL, and MongoDB. I've containerized and deployed services with Docker, Helm, Kubernetes, and GitLab CI/CD, while increasing behavioral test coverage to around 80% with Cucumber.

Previously at Xoriant Solutions, I developed Java backend modules and REST API integrations, delivered UI enhancements, and contributed to Agile testing, reviews, and releases. I'm also building MCP servers that let AI applications securely access enterprise APIs, tools, and business context.
