BLS Visa Appointment Automation System

I am looking for an experienced software developer to build a professional BLS Visa Appointment Automation System for Pakistan, covering three appointment categories: FRV (Family Reunification Visa), EU, and Work Visa. **Technical Requirements:** 1. **Backend Architecture:** Python (FastAPI) or Node.js backend with asynchronous processing. The system should not depend entirely on frontend browser automation. 2. **Real-Time Monitoring:** Continuous or scheduled appointment availability monitoring through authorized APIs or permitted server-side requests. 3. **Fast Slot Detection:** Immediate detection of newly released appointment slots with minimal latency. 4. **Automated Booking:** A streamlined booking workflow with automated form preparation and user confirmation where required. 5. **Multi-Account Management:** Secure management of multiple client accounts and appointment profiles. 6. **Dashboard:** User-friendly web dashboard to manage accounts, visa categories, monitoring status, and booking activity. 7. **Notifications:** Instant alerts through Telegram, email, or other notification channels when slots become available. 8. **Database:** Secure database integration using PostgreSQL or MySQL to manage client information, accounts, and booking records. 9. **Session Management:** Secure authentication, session handling, CAPTCHA support, and protection against session expiration. 10. **Performance:** Efficient asynchronous task queues, error handling, logging, automatic recovery, and monitoring. **Main Objective:** I need a stable, fast, and scalable backend-driven appointment automation solution specifically designed for BLS Pakistan. It should support FRV, EU, and Work Visa categories independently, with reliable slot monitoring and a smooth booking workflow. The developer must provide a working demonstration using the actual BLS appointment workflow before final project approval and payment. The solution must respect BLS access policies, security controls, and booking restrictions.
