I’m building a mobile solution for UK learner drivers that will watch the DVSA booking system 24/7 and automatically swap a user’s existing practical test for an earlier slot—very similar to the service offered at https://testshift.co.uk/. The end result should be a polished, production-ready app that runs natively on both iOS and Android. Core workflow • A student enters their booking reference, licence number and preferred test centres. • A background service polls the DVSA system, searches for earlier cancellations and instantly re-books the first match that fits the user’s criteria. • The user receives a push notification confirming the new time and place; if no earlier slot is found, the scan simply continues. Key requirements • Native apps (or a high-quality cross-platform stack) delivered for both platforms. • Secure handling and storage of personal booking data. • Fast, reliable scraping/API logic that respects DVSA session limits and captchas. • Push notifications for every successful change and for any errors that require user attention. • Clean, intuitive UI that mirrors the simplicity of TestShift while carrying my branding. What I need from you Please respond with a detailed project proposal that covers: 1. Your suggested tech stack and justification. 2. A high-level architecture diagram (mobile, backend, scheduler, notifications). 3. Milestones with realistic timelines. 4. Any similar work or proof of concept demonstrating you can interact with third-party booking systems at scale. I’ll review proposals based on clarity of approach, speed to market and robustness of the solution. Looking forward to seeing how you would tackle this challenge.
