I need a native Windows desktop application that can constantly check United States visa appointment calendars and, the moment a suitable time opens up, lock in the slot automatically. The flow should be simple: a traveller (with an individual login and profile) enters their DS-160 details, selects the consulate and preferred date range, then leaves the program running. In the background the software polls the official site, detects newly released times, and finalises the booking without further input. Core requirements • Runs reliably on Windows 10/11 with an intuitive, lightweight interface • Secure user-account system – e-mail/password login, saved traveller profile, encrypted local or cloud-stored credentials • Real-time slot availability checking at adjustable intervals • Fully automated reservation once a match is found, including form submission and confirmation capture • Logging dashboard that records each check, booking attempt, and final confirmation number Deliverables 1. Compiled installer (.exe) ready for end-users 2. Complete, well-commented source code 3. Setup & user guide (PDF or Markdown) 4. Short video or screenshot walkthrough proving successful test booking in a sandbox or live environment Acceptance criteria • The executable installs and launches on a fresh Windows 11 machine without additional dependencies. • After credentials are entered, the program continuously scans and books a slot within the demo period, saving the confirmation file. • All actions are reflected in the log, and the user can sign out / back in with their profile intact. I am open to the technology stack—C#, .NET 6/7, Python + PySide, or another reliable Windows-friendly framework—so long as it delivers a stable, maintainable solution. If you can also add optional push or e-mail notifications later, note that in your approach, but for now the two key pillars are accurate availability monitoring and truly automatic booking.

Hello I reviewed your Windows US Visa Slot Booker project and it stood out because appointment scheduling software needs reliable availability handling and careful automation without creating duplicate or invalid bookings Problem Visa appointment workflows can be time sensitive and difficult to manage when users must repeatedly check availability manually or when booking logic does not properly handle sessions timeouts and changing slot availability Solution I can develop a Windows application to assist with the appointment workflow using a clear configurable interface, secure session handling, availability checks, notifications, and controlled booking actions where permitted by the appointment system I can implement retry and timeout handling, logging, validation, and safeguards against duplicate submissions while keeping credentials and user data protected Result You will receive a reliable Windows-based appointment assistance tool that reduces repetitive checking and helps users respond quickly when eligible appointment availability appears while respecting the booking platform's rules A few questions Which official US visa appointment system needs to be supported? Should the application only monitor availability and notify users, or also assist with the booking workflow? Which Windows and .NET versions are required? Do you already have the required account and appointment-system access for testing? Thanks

Automating visa appointment monitoring and booking requires careful handling of the official portal’s security, rate limits, and terms, so I’d build this as a reliable Windows application with those constraints designed in from day one. I’d first validate the official portal’s supported automation/access model, then implement the monitoring workflow with controlled polling and robust error/retry handling. Where the portal permits automation, the reservation workflow can be integrated accordingly; otherwise, the app can immediately alert the user when a matching appointment is detected rather than bypassing portal protections. Milestones: Architecture + Windows UI Authentication/profile + monitoring engine Availability detection + notification/logging Booking workflow where permitted Testing, installer, documentation and handover Two questions: Which official visa appointment portal/country flow should be supported first, and does it provide an approved API or documented automation mechanism? I can take ownership from architecture through a production-ready .exe, source code and deployment documentation.

Your project depends on two things working consistently under real conditions: reliable slot detection and safe automated booking without user interaction. The main challenge is not only polling the appointment portal, but maintaining authenticated sessions, handling dynamic page behavior, retry scenarios, throttling, and ensuring the booking flow completes without corrupting user data. I would build this as a native Windows application with a lightweight UI and a background automation engine. A practical approach would be: - Desktop app in .NET 7 (WPF or WinUI) for stability and easy distribution - Browser automation layer using Playwright for resilient interaction with dynamic pages - Encrypted local credential storage using Windows DPAPI - Structured logging system with timestamps, booking attempts, screenshots, and confirmation capture - Configurable polling intervals and booking filters (consulate + preferred dates) - Exportable logs and confirmation history The application would include installer packaging, persistent user profiles, graceful recovery after session expiration, and a clear audit trail for every action performed. I would also structure the automation layer to make future additions such as Telegram/e-mail notifications straightforward. Delivery includes compiled installer, complete source code, setup guide, and a recorded walkthrough demonstrating the booking workflow and logging behavior on a clean Windows environment.
