Simple Backend API for Online Store (No Frontend) I need a small backend API system for my online store. No website or frontend design is required — just the backend that works behind the scenes. What I need it to do: Let me add, edit, and delete products Let me view and manage orders Let me add and manage users (admin and regular) Keep everything secure, so only authorized users can make changes Include a simple way to test and confirm that everything works Technical Notes: Can be built with Python (FastAPI) or Node.js (Express) Use SQLite (or similar local database) for easy setup Include JWT authentication or similar for security Provide Swagger documentation or a Postman collection Must include a README file with clear setup and usage instructions A simple test file/script to verify all endpoints Deliverables: Complete, ready-to-run backend project folder Requirements file (requirements.txt or package.json) README with installation and usage guide Test file or example API calls
