The Challenge

Bridging the Gap

Many academic communities lacked a consistent way for students and alumni to connect beyond campus events. Alumni Connect was built to bring mentorship, career guidance, and community engagement into a single platform with clear role-based access.

Strategic Approach

Problem–Solution Mapping

Data Centralization

Organized alumni and student information in a structured MongoDB-backed directory to make profiles easier to discover and maintain.

Real-time Engagement

Implemented live messaging with Socket.IO so users could communicate directly within the platform.

Career Guidance

Added an opportunities board for jobs, internships, and events to support career discovery in one place.

Platform Integrity

Used authentication and role-based access control to separate student, alumni, and admin responsibilities.

Technical Decisions

Engineering Challenges & Tradeoffs

Real-Time Messaging

WebSockets vs HTTP Polling

Selected Socket.IO bi-directional WebSockets over traditional polling to eliminate unnecessary HTTP overhead and achieve instantaneous chat updates.

Low Latency & Reduced Server Overhead

Authorization System

Central RBAC Middleware vs Inline Checks

Designed a modular JWT middleware enforcing strict access policies (Student, Alumni, Admin) directly at route boundaries for security compliance.

Enterprise Security Standards

Under the Hood

System Architecture

Frontend

React 19 + Vite + Tailwind CSS with a responsive interface and reusable UI components.

Backend

Node.js 18+ + Express.js REST APIs with Socket.IO for real-time communication and backend workflows.

Database

MongoDB Atlas with Mongoose ODM for storing users, messages, events, and opportunities.

Security

JWT authentication, password hashing, and security middleware to protect API access and user sessions.

Containerization

Docker and Docker Compose for reproducible local development and deployment.
