I BuildIntelligentSystems. Deepan Chakaravarthi J, AI Engineer

AI Engineer • Generative AI & RAG • Document AI

I ship production Generative AI on AWS: RAG assistants built on LLMs, Bedrock and Weaviate, and Document AI that catches what regulated teams can't afford to miss.

01 / About Me

I don't just train models.I ship them.

I'm Deepan Chakaravarthi J, an AI Engineer in Chennai with 1.5 years building production Generative AI on AWS. I design and ship Retrieval-Augmented Generation systems with LLMs, AWS Bedrock, Weaviate and FastAPI, and I'm building a Document AI platform that validates PDFs, scans and images for regulated workflows. A backend foundation in multi-tenant SaaS, RBAC and tenant isolation keeps those systems secure, scalable and cost-efficient.

Legal AI Assistant

Mar 2025 – Nov 2025

A RAG-based legal assistant for real-time, multi-turn conversations. Semantic retrieval in Weaviate with optimized embeddings, tokenization and document preprocessing, served by a FastAPI backend on AWS Bedrock LLMs, tuned through prompt engineering to 85–90% response relevance in evaluation tests.

DRT Document Project

2026 – Present

An AI comparison platform for PDFs, scanned files and images in regulated workflows. OCR and computer vision pipelines detect text, value, layout, image and barcode/QR changes, classify each by severity with rules, and feed FastAPI workflows for upload, comparison jobs, review and audit-ready reports.
