I am Yusuf, a French engineer working in the Telco industry.

I sometimes have great ideas which I like to share on GitHub.

Currently, I am developing and maintaining a mature Java (Spring) repository with 200+⭐, which adds a powerful search feature similar to JIRA's JQL, to any REST API with a single annotation.

Assuming you have a Car entity, here is a valid search query to run:

/cars?search= average(ratings) > 4.5 and brand.name in ['audi', 'land rover'] and (year > 2018 or km < 50000) and color : 'white' and accidents is empty

The syntax is very friendly, meaning that an end user can easily write his own query in a frontend application.
Hibernate and MongoDB are currently supported, and other integrations can easily be done thanks to the modular architecture of the project. JavaScript and Angular query builders were also built by generous contributors.

The repository currently has more than 4k views per month, with 10k dependency downloads per month according to Maven Central statistics.

As you can see here, I have solved and given great support to more than 80 issues (feature requests, bugs). That's at least 300 hours of researching, coding, refactoring, documenting, supporting, etc., and to be honest I am really glad to see big tech companies' internal URL's in the statistics.

Your financial support would allow me to focus on these open source contributions by slowly but surely helping me to become independent of my current job.

I am also open to freelance opportunities. You can find my email address on my profile page.
