# Antan Roy on Tal

## Headline

SDE I @Nrolled \| Full Stack & AI Engineer \| TypeScript \| Node\.js \| Python \| FastAPI \| LLM Integration \| 800\+ DSA

## About

Hi, I am Antan\. Backend Engineer with AI integration experience\. I build in Node\.js, Python, and FastAPI — APIs, database design, auth systems, and the plumbing that makes LLM features actually work in production\. On the backend side: PostgreSQL, relational schema design, Row\-Level Security, triggers, Edge Functions, and debugging issues that don't show up in logs\. I understand what's slow and why\. On the AI side: LLM API integration, prompt engineering, and actively building toward RAG pipelines and evaluation patterns\. I'm interested in roles where AI is load\-bearing, not decorative\. 800\+ DSA problems solved\. I debug methodically and ship without heavy supervision\. Looking for Backend or AI Engineer roles at small teams where the backend and AI layers overlap\. 📩 antanroy2002@gmail\.com
