AI Engineer | LangGraph agents, RAG, LLM evals | Ex-Amazon KYC & sanctions | Remote

About

I build applied AI systems focused on grounded answers, reliable agent workflows, and evaluation. Selected work: • groundtruth — A LangGraph vendor due-diligence agent. It cites claims to source passages, runs deterministic sanctions screening, pauses for human review, and uses Postgres checkpoints. 138 tests: github.com/sidharth-cs/groundtruth • SR Astro AI — A Tamil/English AI product running in production for a client, with grounded LLM chat, prompt-injection guardrails, and an evaluation harness: https://app.srastrogpt.com • Voice AI agent — A Python voice assistant using Whisper, GPT-4o function calling, and text-to-speech: github.com/sidharth-cs/voice-ai-agent Before independent work, I spent 2.5+ years at Amazon investigating KYC and sanctions cases, handling 70–100 cases a day. That work shaped how I build AI: verify evidence, handle uncertainty, and escalate when information is missing. Stack: Python, LangGraph, FastAPI, RAG, PostgreSQL, TypeScript, MCP. Chennai-based and open to full-time remote AI Engineer, Applied AI Engineer, and LLM Engineer roles.
