About

I’m Sumit Kumar Java, a full stack developer and RAG/agentic AI engineer with around two years of experience building production-ready services using Java, Spring Boot, Angular, and Python. I enjoy turning real user needs into scalable backend systems, secure APIs, and smooth frontend experiences—while also integrating AI capabilities like RAG pipelines, LLM-based workflows, and agentic systems.

I’ve worked on systems involving authentication and RBAC, automated UI testing, and high-throughput request handling with quotas and rate limiting. On the AI side, I’ve built and trained transformer models, designed book-reading and translation/TTS pipelines with Ollama and Hugging Face, and implemented RAG/agent workflows using tools like LangChain/LangGraph and vector databases such as Chroma. I’m open to full stack and AI engineering roles where I can build end-to-end solutions.
