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.

What I can help with

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.
