Hi, I'm Rajat Pal.
I build production GenAI systems.
AI engineer with 5+ years of experience. I design RAG pipelines, agentic AI platforms, and the backend services that keep them reliable. Right now I'm a forward-deployed engineer helping a US bank take GenAI from idea to production.

Services →RAG systems
Chat-with-your-documents and knowledge assistants that give grounded answers. Ingestion, chunking, embeddings, vector search, and retrieval tuning.
AI agents & automation
Agents that call tools and APIs to automate real workflows, with guardrails, observability, and a clear path to production.
LLM evaluation
Test sets and metrics for retrieval quality, answer quality, and agent behavior, so you know whether a change made things better or worse.
Backend & APIs
Python (FastAPI) or Java (Spring Boot) services, databases, caching, and cloud deployment on AWS.
