About Aniket Chatterjee

with ~2 years of experience building production-grade Generative AI systems for enterprise use cases.I specialize in designing and deploying end-to-end AI systems including pipelines- workflows, and -powered automation solutions. My work focuses on bridging LLM capabilities with real-world systems through robust backend engineering and scalable architectures:• RAG & GraphRAG systems for domain-specific retrieval and reasoning • Multi-agent orchestration using LangGraph for complex workflows • Backend systems using FastAPI for integrating AI into enterprise applications • System optimization (caching, async processing, parallelization) • Reliability improvements using validation layers and human-in-the-loop design I have worked on multiple client-facing AI systems involving automation, reporting, and knowledge-driven assistants — with a strong focus on, performance, and usability:Python • FastAPI • LangChain • LangGraph • Vector Databases • OpenSearch • Docker • AWS
