Java Backend Developer

I am a Java Backend Developer with over 3 years of experience building scalable, secure, and high-performance backend applications.

I specialize in Java, Spring Boot, Spring Security, Hibernate, JPA, RESTful APIs, microservices, Kafka, and event-driven architecture. I have worked on telecom plan management systems and backend services supporting internal users and high-traffic workloads.

I have experience implementing JWT-based authentication, role-based access control, Redis caching, database optimization, pagination, indexing, and API rate limiting. My work has helped improve API performance, reduce query latency, and minimize production incidents.

I am comfortable working with MySQL, PostgreSQL, Docker, Kubernetes, AWS, Jenkins, Git, CI/CD processes, and observability tools including ELK Stack, Prometheus, Grafana, and Zipkin.

I also have exposure to generative AI development with Spring AI, OpenAI APIs, RAG, vector databases, embeddings, semantic search, AI chatbots, and document question-answering solutions.

I enjoy solving backend and system design problems, automating operational workflows, and collaborating with stakeholders to deliver reliable production-ready software.
