What topic for a diploma to choose on the web?

Question

IT education

I welcome everyone.
I am looking for a topic for my master's thesis. I chose web development, but haven't chosen anything concrete yet.
I myself study Java, Spring, JavaScript, React. It would be quite interesting to write a backend on something else, but not necessarily.
I wanted to write some idea as an example to show that I myself came up with something, but somehow I didn’t come up with it yet :)
Ideally, something that could not only be passed as a diploma and thrown away, of course :)

Answer 1

Write a theme generator for diplomas. Based on the specialty, with an analysis of the work of specific universities, statistics and other tinsel.

Answer 2

Especially now life has gone online. I'm tired of choosing, monitoring and maintaining platforms on all my devices: skype, zoom, vk, telegram, whatsapp, signal, vk, facebook, gmail, tox etc... I would probably like an aggregator that would pour me a unified information flow from all sources in one tape ...
