Project description:
"I need a web-based portal that exposes clean, well-documented APIs for three core services: mobile recharge, utility bill payments and DTH recharge. The front-end can stay minimal—as long as it lets me configure plans, view transactions and monitor service status—but the back-end must be production ready from day one.

Core expectations
• REST or GraphQL endpoints that handle the full payment flow for each service
• A browser dashboard where I can add or suspend operators, set commissions and review logs in real time
• Secure authentication (token or key based) and role management so I can grant limited access to external partners
• Clear, versioned API documentation generated automatically from the codebase

Acceptance criteria
1. I can complete a successful test recharge or bill payment from the documentation alone.
2. Transaction and error logs are visible in the web panel within seconds of the call.
3. Source code is organised, commented and deploys to a standard cloud stack (Linux, MySQL/PostgreSQL, Node/PHP/Python—your choice).
4. A short hand-off call or screencast shows the deployment process and where to adjust future service providers.

If you already have experience with payment gateways, operator mapping or high-volume API traffic, your insight will help us move faster." (client-provided description)
