Need help with design suggestions for my app

Hey guys, I'm developing an app for managing general assemblies using Spring and Angular. Users need to input assembly details (Type, Year, Date, Time, Address, City) and attach files (route sheet, invitation letter, attendance sheet, proxy, attendance form). Actions and their details are extracted from the uploaded Excel route sheet and displayed on a management page. Users can also attach deliverables to actions. Can you suggest a design for this?...

Does anyone use Drizzle here? Many-to-Many relationships and types

Consistent Hashing

What's the best way to implement consistent hashing in a database that doesn't have this feature by default, in my setup I have a bunch of nodes in a zookeeper path and when I retrieve all the nodes i hash a key and decide which node to place a user own, should my consistent hashing algorithm exist in my application code? And how I go about remapping the keys in the db

.Net 8 Database Interfaces

I'm working on my budget app and have come to the point where I need to use a database (SQLite specifically). I'm debating between using Microsoft.Data.Sqlite or just biting the bullet and using Entity Framework Core. The database tables are not very complex so the SQL statements won't be that verbose, but most places (from my research) use EFCore. But I don't like/understand EFCore (maybe some correlation/causation there :p). Thoughts?...

Making my first full stack website, and I want an authentification system

So I wanna make my first big fullstack project, and between the backend functionalities, I need an authentification system, the thing is that making it all by hand is extremely long and prone to being extremely not secure. I want my first project to have a good level of security. Is it okay to use a library like NextAuth or Firebase Auth for it? Will I still be learning or will it do everything for me? Cuz I want to learn from my fullstack project to some extent, and if these auth services do everything for you in one click isn't that counterproductive? People online do say that it's very recommended to use services because they were built by pros that know how to make them secure and flexible, and in the future I plan on using them again, but how will that look like in the eyes of companies that might hire me or if I want to freelance?...
