Overview

CS-AI is a full-stack AI chat application deployed on Vercel with Firebase as the backend. It supports multiple AI models, Google and email authentication, per-user token quotas enforced server-side, persistent chat history, and a full admin panel for managing users and tiers.

Context

I wanted to build something that felt like a real product, not just a demo. The core challenge was making multi-model AI accessible while keeping it controlled. Different users get different access levels and every request is authenticated and rate-limited before it ever reaches an upstream API.

I built the entire stack myself: the chat UI, the serverless API layer that proxies Gemini and OpenRouter, the Firestore schema, the token quota system, and the admin panel. Streaming responses were handled via Server-Sent Events with a filter that strips internal model reasoning before it reaches the user. Rate limiting runs on Upstash Redis at 20 requests per minute per IP.

Overview

Notes AI is a web app that turns any topic, pasted text, or uploaded PDF into clean structured study notes using Google Gemini. It supports four note styles — Structured, Bullet Points, Cornell Method, and Mind Map — and lets you export everything as a formatted PDF or Markdown file in one click.

Context

The problem I kept seeing was students drowning in messy, unstructured notes that were hard to revise from. I wanted to build something that took whatever you had — a topic, a wall of text, a lecture PDF — and gave you something actually usable in under a minute.

The PDF export runs entirely in the browser using jsPDF with dark-themed pages, proper heading hierarchy, and accent-colored markers. The API key is stored in .env only — it never touches any server other than Google's.

Overview

Student Data Administration System is a desktop application built entirely in Java using AWT and Swing, backed by a MySQL database hosted on Clever Cloud. It provides a clean role-based interface for school and institute administrators to manage student records with access restrictions enforced at the class level.

Context

The goal was to build something that worked like a real internal tool, not a prototype. Authentication uses BCrypt hashing so passwords are never stored in plain text. The dashboard renders all student records in a scrollable, sortable table with live search across name, class, roll number, and mobile.

Student management is gated behind the Admin role with confirmation dialogs to prevent accidental deletions. The Admin Panel lets admins create new user accounts, change roles, reset passwords, delete users, and configure per-user class access restrictions. The entire stack was written and packaged by me as a fat JAR and wrapped into a signed Windows executable. Built and validated against 150+ official Cusrow Wadia Institute of Technology student records.

Overview

CS Mart is a multi-page e-commerce frontend built entirely with HTML and CSS. It is structured as a storefront with a homepage, product listing page, about page, contact page, and a registration form. The product cards display item names, original and discounted prices, percentage-off badges, and a buy button modelled after real shopping platforms.

Context

The goal was to build a complete, navigable website from scratch without any frameworks or libraries — just HTML and CSS. Each page shares a consistent navigation bar. The homepage acts as a landing page. The product listing page renders eight cards across categories like vehicles, electronics, and bikes, each with discount labels.

The registration form collects name, email, phone, address, password, gender, hobbies, department and date of birth with client-side validation via HTML5 attributes. The entire layout uses flexbox for structure.
