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
