Selected Projects

End-to-end systems built for real clients and academic research — focused on architecture, scalability, and measurable outcomes.

01 / AI SYSTEM

Autonomous Research Pro

RAG Pipeline · LLM · Full Stack

Problem: Researchers spend hours manually aggregating and cross-referencing web sources. Solution: An autonomous AI assistant that crawls, indexes, and synthesizes web data into verified, source-attributed research reports — exported in IEEE format. Built on a RAG pipeline with a local Qwen2.5 LLM (Ollama), FastAPI, and a React frontend. Every AI-generated statement is traceable to its source.

FastAPIOllama / Qwen2.5RAG SQLAlchemyMySQLBeautifulSoupReact
  • Local LLM inference — zero API cost, full data privacy
  • Source-tracked Q&A over auto-generated reports
  • IEEE-style paper export pipeline
  • Async FastAPI for concurrent web crawling

02 / AI AGENT

Company Intelligence Agent

Web Scraping · NLP · Business Intelligence

Problem: Sales and BD teams waste hours manually researching prospects. Solution: An AI-powered scraping agent that takes a company domain, autonomously crawls its public web presence, and extracts structured intelligence — services, clients, team, positioning — using a local LLM for NLP categorization. Outputs structured JSON profiles via a React dashboard.

  • Fully autonomous multi-page web traversal
  • LLM-driven entity extraction and categorization
  • Structured JSON output for downstream integration
  • Ethical scraping of publicly available data only

03 / FULL STACK PLATFORM

TNPSC Learning Hub

SaaS EdTech · REST API · Auth System

Problem: Students preparing for Tamil Nadu PSC exams lacked a centralized, structured digital platform. Solution: A full-stack learning management system with role-based access, adaptive exam modules, video streaming, and real-time progress analytics. Designed for scale — RESTful API architecture with JWT-based stateless auth and MySQL relational schema.
