Payment Integration: - One-Time Payment: Secure payment options (e.g., Stripe, PayPal, Razorpay, etc.) to allow users to pay for individual calculators. - Payment History: Users can view their past transactions in their account dashboard. #4. Technology Preferences: - Frontend: Clean, responsive, and fast-loading design (Bootstrap, Tailwind CSS, or any modern framework). User-friendly UI: Focus on simple and intuitive navigation. - Backend: A reliable framework (Node.js, Laravel, or Django preferred). - Database: Robust and scalable database (MySQL, PostgreSQL, or MongoDB). #5. Admin Features: - Admin panel to manage calculators, view users, and oversee payments. - Easy calculator addition: Admin should be able to add or update calculators via the backend. #6.

Basic training on using and maintaining the platform. 4. Post-development support for minor tweaks and bug fixes (optional, based on the developer’s offer). --- Additional Notes: - I can provide examples of the type of calculators to be integrated. - The website should be SEO-friendly to ensure visibility in search engines. --- Budget and Timeline: - Budget: Provide your estimated cost for this project. - Timeline: Ideally, the project should be completed within [insert your preferred timeline, e.g., 4-6 weeks]. --- How to Apply: Please provide: 1.
