I build Generative AI, GraphRAG, and backend platforms for document intelligence and retrieval.
IndiaWhat I'm looking for
At Power Grid Corporation of India Limited, I built a document question-answering chatbot using GraphRAG, Python, LLM APIs, Neo4j, and FastAPI. I developed ingestion, PDF extraction, chunking, embeddings, semantic retrieval, and graph-based retrieval pipelines.
I've also built a distributed RAG-as-a-Service platform with Spring Boot microservices, Kafka pipelines, Redis caching, vector database retrieval, and an API Gateway with Resilience4j circuit breakers, reducing average query latency by about 40%.
As a B.Tech CSE (AI & ML) student, I build practical AI systems spanning multimodal retrieval, machine learning clustering, REST APIs, NLP, and knowledge graphs.
