Customer register.

I need a web page to handle customer registers. -It must be in python back end. User/password login. -Should be used from any device (phone, notebook, tablet, etc) -The DB can be sqlite. The customer register should have the following fields: name. birth date. phone. (phone must be in another table, as a customer can has more than 1 phone, so the relationship would be 1 to many) policy field - which will handle a file, PDF or DOC. -Basic admin panel, to add, modify and remove customers, upload the file (policy field) -Modern web front end, icons like whatsapp or telegram. -optional- multi language.
