Question Bank Website Developer Needed

I am looking to hire a freelancer or development team to build a subscription-based question bank web app for ophthalmology residents. I currently have approximately 2,000 original multiple-choice questions in a Word document, and I need the platform built around this content. The platform should include: * User accounts: signup, login, forgot password * Paid annual subscription access through Stripe * Question bank functionality: categories/tags, images, answer explanations, and review mode * Timed exam mode: users can choose topic(s), number of questions, randomized questions, and review answers at the end * Analytics dashboard: overall performance, category-based performance, and quiz history * Admin dashboard: add/edit/delete questions, manage users, and import questions from CSV * Percentiles and/or anonymous leaderboards * Comments under each question with basic moderation * Mobile-friendly design * Secure database and user authentication An example of a similar platform is OphthoQuestions: https://www.ophthoquestions.com/ Please include the following in your response: 1. One or two examples of similar work you have built, such as a subscription web app, exam/quiz platform, learning platform, or admin dashboard. 2. The tech stack you would recommend and why. 3. A rough estimate of cost and timeline. 4. Your approach to importing the existing question bank content. 5. Ongoing maintenance options after launch. 6. Whether you can provide documentation and support for future updates. Important: I must own the domain, hosting accounts, database, content, and full source code. The project should be built in a way that allows another developer to maintain or modify it in the future.
