Hard Rejection : the codebase feels completely unfinished and rushed.

I have created OTP login & registration with Resend OTP & full admin access & control
6 SMS gateway supported & with custom http api option almost 99% of SMS gateway support within just a minute of copy api url and save it.
Full Admin & User Demo.
1st time they said its a soft reject because they need credential to test after i provide all the things and mention even in script after testing it they said
Hard Reject : the codebase feels completely unfinished and rushed.

Hello!

I think that this comment is clear enough and does not require additional explanation.
Most likely your code is poor quality and difficult to modify.

But @Codewayfarer i have used complete procedural pdo language and sanitize all the data which prevent xss and sql injection.
