Which tool should I use to build a simple dynamic website in 2020?

Experienced C programmer here. I need to build a very simple website for personal usage with: - Password-protected login to hide every single page behind - A single sqlite database with possibly a single table (maybe a second single-line table to store my login + pw-hash + salt) - A single page to upload stuff to the database.

I really like Ruby as a programming
