πŸ“Œ Featured Projects

🧠 MindSpace: AI-Powered Mental Wellness Platform

Built "Mimi," an AI chatbot providing context-aware mental health support using a custom RAG pipeline and Pinecone for vector storage. Designed a hybrid database (MySQL & MongoDB) to guarantee ACID compliance for user data while scaling chat logs for 100+ concurrent sessions. Constrained LLM outputs strictly to verified psychological datasets to mitigate hallucinations. πŸ† Secured a Top 100 finish among 500+ teams and 3,000+ participants at MumbaiHacks (Dec 2025).

πŸ“„ IntelliDocs: AI Document Analysis System

A full-stack document analysis platform that automates text summaries using Local LLMs (Ollama) to entirely eliminate external API costs. Architected a robust data pipeline using PyMuPDF and Cloudinary, converting documents into vector embeddings stored in TiDB. Launched on AWS Lightsail (50+ signups), engineering a secure tunneling architecture to bypass free-tier hardware constraints.

πŸŽ™οΈ DevScribe

A voice-first Agentic IDE framework built with a Python/FastAPI backend that generates and manages project scaffolding using a browser-based speech transcription layer, featuring an autonomous self-healing script loop.


πŸ† Achievements & Certifications

  • πŸ₯ˆ First Runner-Up: Promptverse 2.0 organized by Fore School of Management (FSM), New Delhi (2026).
  • πŸ… National Finalist: Mind the Product organized by E-Cell, IIT Roorkee (2026).
  • 🎀 Special Memento: DevScribe Agentic IDE Pitch at the "AI for Viksit Bharat" national seminar, SC&SS JNU (2026).
