At Stackbit Internet Services Pvt. Ltd., I architect MCP-based agent integrations that expose internal operational actions through controlled Python services and JSON-RPC contracts. I also implemented FastAPI and PostgreSQL-backed services for agent state, execution history, audit records, and persistent sessions.
I built a production-grade RAG research assistant combining pgvector dense retrieval with PostgreSQL full-text search and Reciprocal Rank Fusion. I evaluated it against a 50-document corpus and 26 benchmark queries, measuring Recall@5 of 0.9776 and MRR of 1.0000, and validated the retrieval path under k6 load testing.
