Web Development for Automatic VPN Deployment and Sales Platform

Job Description:
We are looking for a skilled developer or development team to build a fully automated VPN deployment and sales platform. This project requires only web front-end and back-end development; no VPN client is necessary.

The platform should allow customers to automatically deploy VPNs through the following process:

Project Requirements:
Automatic Deployment by Region and Protocol

Customers select a regional server and preferred network protocol (L2TP, PPTP, Shadowsocks, SOCKS, VMess, VLESS).
Deployment uses random port allocation.
Customers can manage nodes to change protocols post-purchase (e.g., clear the original protocol and redeploy with a new one).
Inventory Management and Purchase Process

Customers can choose server quantities based on available inventory in their chosen region.
Utilize ctyun.cn API for automatic server purchase after payment confirmation.
Servers come with fixed specifications (CPU, memory, bandwidth, etc.); customers can only select the region.
Tunnel Server Purchase and Deployment

Provide an option for customers to purchase tunnel servers that can be configured for transit purposes.
Enable automatic deployment for tunnels, allowing users to set IP and port for transit as needed.
Use huaweicloud.com API to manage server purchases and configuration.
Servers in mainland China and Hong Kong are billed by data volume (fixed at 300M bandwidth).
Residential IP Purchase

Integrate a page for purchasing residential IPs for regions outside of China.
Use the ip2world.com API to support IP purchasing.
Prepayment Requirement

Implement a prepayment system to prevent server deactivation. If payment lapses, the server should automatically release based on the cloud provider's policies.
Activation Fees for VPN Nodes

For China region VPN node purchases, customers must pay a 300 RMB activation fee per 20 nodes before purchase is allowed.
Multiple activations should be supported (e.g., for 60 nodes, pay 900 RMB for activation).
For Hong Kong transit tunnel purchases, a one-time 300 RMB activation fee is required, with no node limit.
Agent Promotion and Discount System

Create a multi-tiered agent promotion system.
Upper-level agents can adjust the discount percentage on purchase payments for their lower-level agents.
Includes an application and approval process for agent discount adjustments.
Additional Requirements:
User Authentication: Option for customers to add an Authenticator token after account registration.
API Integrations: Expertise with integrating APIs (ctyun.cn, huaweicloud.com, ip2world.com).
Responsive Design: Ensure the platform is responsive and optimized for various devices.

Payment using the usdt trc-20 API

The theme language is Simplified Chinese, and can be switched between Chinese and English.

The above transactions are conducted in RMB, and the payment is converted to USDT TRC20

You need to bring your own language translation, the main language is Simplified Chinese!
