PROJECTS

AI Mental Health Chatbot Jan 2026 – May 2026

Tech: Python · Flask · PostgreSQL · OpenAI GPT-3.5 · LangChain · Pinecone · HTML/CSS/JS · Vercel · Render

• Co-designed a full-stack RAG chatbot using OpenAI GPT-3.5 and LangChain, delivering contextual, empathetic mental health guidance backed by 500+ hand-curated knowledge sources.

• Integrated Pinecone vector similarity search, improving retrieval relevance by ~40% over keyword-based systems.

• Built a Flask REST API with PostgreSQL backend featuring session management, a suicidal ideation classifier, and content filtering — ensuring production-level security.

• Hardened the application with HTTPS, input sanitization, and rate limiting; deployed on Vercel and Render with <2s average response time under concurrent load.

Assistance for On-Road Vehicles System Jul 2025 – Oct 2025 Tech: PHP · MySQL · HTML · CSS · JavaScript · Geolocation API

• Built a service marketplace connecting stranded motorists with nearby service providers in real time using the Geolocation API.

• Implemented a fully responsive, single-page-style UI with live service request tracking — no page refresh required.

• Designed a normalized MySQL database and PHP backend with role-based authentication for both users and service providers.

Expense Tracker — IBM Hack Day Jan 2026 – Feb 2026 Tech: HTML · CSS · JavaScript

• Built a browser-based expense tracker from scratch supporting add/remove expenses, category tagging, and live balance display.
