Key Features & Contributions:

1. WireGuard-Based VPN Service:

• Integrated WireGuard, a modern VPN protocol known for its simplicity, speed, and security, to establish fast and secure connections between users and VPN servers.
• Developed custom Python scripts to manage WireGuard configurations, allowing for efficient connection handling, key exchange, and encryption.

2. Backend API for VPN Management:

• Built a robust RESTful API using Python and Flask/Django to handle core VPN functionalities such as user registration, authentication, connection management, and subscription plans.
• Ensured the API supports multiple endpoints for server selection, VPN connection monitoring, and data usage tracking, providing a complete management system for users and administrators.
• Integrated real-time charts with D3.js and Recharts, allowing users to interact with visual data through features like zooming, panning, and tooltip hover details.

3.User-Friendly Angular Frontend:

• Developed an intuitive and responsive front-end using Angular, providing users with an easy-to-navigate dashboard to manage their VPN connections, choose server locations, and view real-time connection statistics.
• Integrated Material Design principles to ensure a clean and modern UI, enhancing user engagement and usability across devices.

4.Global Server Network and Location Selection:

• Configured VPN servers across multiple regions (e.g., North America, Europe, Asia) to ensure fast and reliable connections regardless of the user's location.
• Built a server selection feature that allows users to manually choose their preferred VPN server based on location or automatically connect to the fastest available server.

5. End-to-End Encryption and Data Privacy:

• Implemented end-to-end encryption using WireGuard’s cryptographic protocols to ensure secure transmission of user data over the VPN.
• Configured privacy-first features, including a strict no-logs policy, ensuring that user activity is never tracked or stored.

6.Secure User Authentication and Account Management:

• Integrated OAuth2 for secure user authentication, allowing users to log in via Google or other social platforms or create standalone accounts.
• Developed user account management features where users can view their connection history, subscription status, and manage account settings, including resetting credentials and updating personal information.

7. Subscription Plans and Payment Gateway Integration:

• Implemented multiple subscription tiers (e.g., monthly, yearly) with different levels of access and bandwidth limits.
• Integrated payment gateways such as Stripe and PayPal for secure transactions, allowing users to subscribe or upgrade plans directly from the platform.

8. Automatic VPN Connection on Startup:

• Designed a feature allowing users to set automatic connection to the VPN on system startup, ensuring that their internet connection remains private and encrypted from the moment they go online.
• Added a kill-switch functionality to block internet traffic if the VPN connection drops, further protecting user privacy

9.Real-Time Monitoring and Analytics:

Developed real-time analytics on the front-end that show active sessions, connection duration, bandwidth usage, and server load.

Integrated WebSockets to provide live updates on VPN performance, ensuring users can track their connection status without refreshing the dashboard.

10.Server Provisioning and Automation with Ansible:

• Used Ansible to automate the deployment and configuration of VPN servers, allowing the team to rapidly scale the infrastructure by deploying servers in new locations as user demand increases.
• Implemented automated monitoring and alerting systems to maintain high uptime and quickly resolve any server issues.
