🚀 Building a Secure & Scalable Airport Management System
I’m currently developing a full-stack Airport Management System using React.js, Node.js (Express), and MySQL, with a strong emphasis on security, role-based access control (RBAC), real-time communication, and scalable system architecture. This project is designed to simulate real-world airport operations by integrating multiple departments into a single secure platform.
✈️ Project Overview
The system brings together key airport departments:
Administration
Operations
Ground Staff
Passenger Services
Safety & Security
Reporting
Each module is protected using Role-Based Access Control (RBAC), ensuring users can only access features permitted by their assigned roles, following the principle of least privilege.
🔐 Authentication & Authorization
Google Single Sign-On (OAuth 2.0)
Automatic user creation on first login
Role-based access validation at UI, API, and WebSocket levels
Two-step verification using OTP for enhanced security
🧾 Ticket Booking System (MySQL Persistence)
Ticket bookings are permanently stored in a MySQL database
Booking data persists across page refresh, logout, and server restarts
Passenger and Admin dashboards fetch data directly from the database
Supports PDF ticket generation using stored booking details
✈️ Live Flight Streaming (WebSockets)
Real-time updates for arrivals, departures, delays, and gate changes
Secure WebSocket authentication using tokens
Role-specific live dashboards and instant alerts
🤖 Role-Based Chatbot
Integrated chatbot within the dashboard
Provides role-aware responses and limited command execution
Backend validation prevents unauthorized or privileged actions
☁️ Cloud Storage
Secure storage for system logs, reports, and audit trails
Role-based access to stored resources
Designed for future analytics and reporting extensions
🛠 Tech Stack
Frontend: React.js
Backend: Node.js (Express)
Database: MySQL
Authentication: Google OAuth 2.0
Real-Time: WebSockets
Cloud Storage: AWS S3 / Firebase
🚧 Challenges Faced
Maintaining RBAC consistency across UI, APIs, and real-time events
Securing chatbot-triggered workflows
Handling real-time data streaming efficiently
Designing scalable and secure backend architecture

🚍 School Bus Management System – Project

Karthika.v Tkm — Sat, 07 Feb 2026 17:30:56 +0000

I’m excited to present my project on a School Bus Management System, designed to enhance student safety and streamline school transportation operations.

#ProjectShowcase
📍 GPS Tracking Integration
A major feature of this system is Real-Time GPS Tracking, which allows schools and parents to monitor bus locations live and receive accurate updates.
🔹 Key Features:
🚌 Bus & Route Management
📍 Live GPS Tracking with Map View

⏱️ Estimated Time of Arrival (ETA)
👨‍🎓 Student Pickup & Drop Attendance
👨‍✈️ Driver & Staff Management
🔔 Instant Notifications & Alerts
📊 Admin Dashboard & Reports
🎯 Objective:
To improve student safety, reduce transportation delays, ensure transparency, and enhance communication between schools and parents.
💡 By integrating GPS technology, the system provides real-time visibility, better route optimization, and emergency response support.
Open to feedback and suggestions. Let’s connect!
