# Rounak Banerjee on Tal

## Headline

Software Engineer who builds AI systems that actually answer questions \| Python, FastAPI, RAG, LLMs

## About

I build applied AI systems — from retrieval\-augmented generation pipelines to production\-facing tools — and I like shipping things people actually use\. Most recently, I designed and built Meridian, an enterprise knowledge assistant using hybrid BM25 \+ semantic search \(FastAPI, ChromaDB, sentence\-transformers, Groq's Llama 3\.3\-70B\) to cut manual document lookup time in a RAG\-based Q&A workflow\. I followed that by building an AI\-powered invoice\-PO matching and validation tool \(FastAPI, React, Groq API, SQLite, Airtable, JWT auth\) that automated a manual reconciliation process end\-to\-end, complete with a full submission package — architecture docs, demo video, and slides\. I'm a published researcher in secure wireless communications for defense applications, and I served as Research Head and Mentor at the Association for Cyber Security — directing research strategy and mentoring interns through the ACS Dev\+Sec 2\.0 program — alongside serving as President of the ISTE Student Chapter at TOCE\. I'm an Information Science Engineering graduate \(2026\) actively looking for AI/ML and GenAI engineering roles where I can keep building systems end\-to\-end\. 📫 Open to connecting — reach me at rounakbanerjee0204@gmail\.com or check my work on https://github\.com/BookishThumb\.
