Need guidance and help for adding backend to my college project .

I want a coder or developer who can help me to integrate simple firebase backend in my wesite/webapp project to showcase in my college. The app is a self driven attendance tracker where any students can track his attendance in detailed statistics. But i m not a developer or ui designer i m just a commerce student . I designed the entire ui of this webapp , every page via the llm model . I have now all pages and ui flow code in simple vanilla html , css and js . But in a separate files . Each ui flow has entire new [login to view URL] file with its own html , css , js . So now i want help to integrate those file as single ui flow . And after integration help me to add logic and required backend so the webapp goes production ready . And usable by user .
