Chirag A.

Top Rated AI engineer with 100% Job Success, RAG systems, AI agents, and production LLM applications shipped on time, under budget. I lead AI delivery at IndaPoint Technologies, where I've personally architected 16+ production AI systems across healthcare, legal, HR, and ad-tech. Recent client work includes a $9.7K Custom GPT engagement (5-star, repeat client) and AI-integrated mobile apps with end-to-end ownership. What I build for clients on Upwork: - RAG systems grounded on your private data, LangChain, LlamaIndex, OpenAI, Claude, Pinecone/Weaviate/pgvector. Auditable, hallucination-resistant, production-tested. - AI agents and workflow automation, multi-agent systems with LangGraph for document processing, lead qualification, research automation, and ops workflows. - Custom GPTs and LLM integrations, fine-tuning, function calling, MCP-style tooling that connects AI to your internal systems. - AI-powered web and mobile apps, React, Next.js, FastAPI, Flutter, Node.js. AI woven in as native intelligence, not a feature added afterward. How I work: Fast discovery, clear scope, prototype within days, production engineering with testing. I flag risks early and ship without surprises. Strong written and spoken English; comfortable on calls with technical and non-technical stakeholders.
