VFS Visa Appointment Automation System For clients in Turkey- Project Overview We are seeking an experienced developer to design and build a scalable, secure, and fully automated web application that monitors VFS Global visa appointment availability and automatically books the earliest available slot. The system will be used by multiple agencies and applicants, and must operate reliably under anti-bot measures and rate-limiting constraints. Core Objectives The system should be capable of: Continuously monitoring VFS Global appointment calendars Detecting newly available slots in real time (or near real time) Automatically booking the earliest available appointment Simulating human-like behavior to minimize detection risk Supporting multiple agencies, users, and applicant profiles Maintaining a modular, scalable, and well-documented architecture Technical Requirements Web-based application (Python required) Preferably built with Playwright (Selenium acceptable) Fully containerized using Docker Linux-based deployment Headless-first architecture Optional VNC/Docker VNC access for debugging and monitoring Clean, modular, and well-documented codebase User Roles & Access Control Admin Panel Role-based access control (RBAC) Create and manage agency accounts System-wide configuration and monitoring Agency Users Manage multiple applicants Support different visa types and applicant profiles Trigger automated booking jobs using saved data Automation & Intelligent Behavior Periodic and automated appointment checking Ability to maintain active sessions during high-demand periods Instant booking upon slot availability Human-like interaction features: Mouse movement simulation Typing delays and behavioral patterns Randomized wait intervals Optional virtual keyboard usage Browser fingerprint and session isolation Session & Proxy Management Secure, isolated browser contexts Multiple concurrent sessions without conflicts Proxy rotation and fallback strategies Proxy list management via admin panel Security & Stability Strong exception handling and auto-recovery mechanisms Protection against account bans (rate limiting, randomized behavior) Retry logic with alternative profiles Resilience against portal UI/DOM changes Client & Appointment Management The system should include a structured module to manage client information and appointment details in a clear and organized manner. Appointment Information & Dashboard The system must store and display detailed appointment data for each client, including: Appointment date and time Application center (location) Visa category/type Booking status (Pending, Booked, Failed, Cancelled) View client statuses in real time Filter by visa type, country, or booking status Monitor booking progress efficiently Logging & Notifications Detailed logs for: System activity Booking attempts Successful reservations Portal availability status Notification channels: Email Telegram Configuration & Extensibility User-friendly configuration system Support for multiple visa types and applicant profiles Extensible architecture for: Additional notification channels External CRM integrations (optional) Custom automation rules Development Approach Third-Party Services No mandatory third-party paid services If any external services are required, they must be clearly stated and justified Important Notes for Applicants Please include in your application: Examples of similar automation, booking, or scraping projects Technologies you used in those projects Your proposed technical approach Estimated timeline and milestones This project will be developed milestone-based, starting with a Proof of Concept (PoC).
