e-Vote: An Offline-First, Electronic Voting System for Academic and Institutional Elections

e-Vote is a modern, secure, and resilient digital voting platform designed for academic and institutional elections. The system aims to provide a trustworthy, accessible, and offline-capable voting experience while maintaining transparency, integrity, and ease of administration.

🛠️ Tech Stack

The project is built with a modern full-stack architecture focused on reliability and scalability:

• Next.js 16 with the App Router
• React 19 and TypeScript
• Clerk for authentication and secure access control
• Supabase for PostgreSQL database, real-time data handling, and Row Level Security
• CSS Modules for polished, component-based UI styling
• Mermaid for flow and system documentation

🎯 Problem We Are Solving

Traditional voting processes in academic institutions often face several challenges:

• Manual or paper-based voting is slow, error-prone, and difficult to audit
• Limited access to secure digital participation for students and staff
• Vulnerability to duplicate voting, tampering, and inconsistent record keeping
• Poor resilience in environments where internet connectivity may be unreliable

💡 Solution

e-Vote addresses these issues by providing a digital election platform that is:

• Secure and authenticated through institutional identity management
• Designed to support fair, verifiable voting processes
• Structured for offline-friendly operation and future synchronization workflows
• Easy to manage for administrators, candidates, and voters

✨ Key Features

• Secure voter authentication and role-based access
• Election and candidate management for administrators
• Student-facing dashboard for active and upcoming elections
• Vote verification and receipt support
• Offline-ready architecture for resilient institutional deployments
• Audit-friendly data structure for review and accountability
