What I'm looking for

I'm looking to build production-grade Java backend systems and microservices, deepen my system design skills, and contribute to next-generation applications using Generative AI.

At Tata Consultancy Services, I build a claim processing system that supports end-to-end insurance claim workflows through RESTful APIs using Java, Spring Boot, and Maven.

I improved claim-status retrieval with Redis caching and built Kafka producer-consumer pipelines that trigger automated email notifications. I also secure protected endpoints with OAuth2 and JWT, while using Log4j2 and Splunk for centralized monitoring.

In a personal LinkedIn-style microservices platform, I architected seven Spring Boot components for users, posts, connections, notifications, uploads, service discovery, and API routing. I implemented social features, JWT authentication, BCrypt password hashing, PostgreSQL transactions, Neo4j connection queries, and Kafka-driven notifications.

I'm focused on production-grade backend systems, system design, and maintainable microservices, while growing my work with LLMs, RAG, prompt engineering, embeddings, vector databases, and Spring AI.
