The reputation of funded projects is very strong because they have secured substantial funds and are backed by ventures.
There are so many projects that are open source, and you should definitely contribute to those especially because their credibility is way higher.
There might be a chance where you can get a direct job offer, after all, you don't really know who is watching you in open source!
I've kept only active projects (last commit under 2 months) so it will be useful. Let's keep it short and straight.
1. Taipy - Data and AI algorithms into production level web apps.
Taipy is the perfect Python library for easy, end-to-end application development, featuring what-if analyses, smart pipeline execution, built-in scheduling, and deployment tools.
It's used for creating a GUI interface for Python-based Data & AI applications and improving data flow management.
The key is performance and Taipy is the perfect choice for that especially when compared to Streamlit. You can read the detailed comparison of Taipy vs Streamlit by Marktechpost.

2. Hoppscotch - API Development Ecosystem.
Hoppscotch is a lightweight, web-based API development suite. It was built from the ground up with ease of use and accessibility in mind.
Hoppscotch is very similar to Postman but provides a few different features. This is what the dashboard looks like and you can test things live at hoppscotch.io.
Postman requires you to be online even for testing local APIs. With Hoppscotch, you can work with your APIs without an internet connection.
Even the web app operates offline by caching locally and functioning as a PWA, allowing you to test APIs anywhere, anytime!
Hoppscotch also provides a private workspace. See the list of complete features.
The best part and necessary one is that they provide complete docs which includes guides, articles, support, and a changelog so you can see all of the stuff here.
