The front-end of my web application is finished and running; what remains is a solid PHP backend that connects everything and powers the AI chatbot I built. I’ve already settled on MySQL for the database layer, so you’ll design the schema, write the queries, and set up migrations or scripts that load cleanly into that environment. Core features I need are straightforward but must be production-ready: secure user authentication (signup, login, password reset) and full CRUD operations for the main data entities used by the site. The chatbot will interact with the same data through direct database access, so whatever you build must expose well-structured tables and relations the bot can read from and write to without extra middleware. Because the front end is complete, you can focus entirely on server-side code, database design, and configuration. Clear documentation and a short hand-off walkthrough will be the final step so I can maintain or extend the codebase after delivery. Deliverables • MySQL database schema and creation scripts • PHP backend code implementing authentication and CRUD endpoints/controllers • Integration instructions confirming the chatbot can read/write via direct DB access • A brief setup guide and any credentials or environment variables required Once these pieces are in place and tested end-to-end, the project is complete. I’m available for quick answers and can spin up a staging server the moment you need it.
