Can somebody suggest me backend heavy opensource projects which I can contribute to improve my engineering skills?

I had a machine coding round today for backend role but I didn't not show up cause I was nervous as hell. Reason, I failed my last 2 interviews.

Now, I'm conflicted, sad, anxious and somewhat devastated.

Hey Engineers/Developers,
I want to practice my backend skills and learn how scalable applications are built. So what I'm thinking to do is learn the high-level system design first and try to implement that learning as well.
Suppose I learned how Instagram reels/TikTok works, how they process, and how they scale to millions of users around the globe by trying to build my own scalable app.
Or I can already contribute to established open-source projects, for example, rocketchat.

What should I do?

In my current job, I feel like I'm not learning much as it like I'm stuck. I also want to work at Google, which has been a childhood dream of mine. Additionally, my upper management promote on using GPT to write code which I feel like it's not a good thing as a younger professional seems like my development skills is depricated. The worst part is that I'm unable to allocate time to learn new things on my own. I want to leave this job to focus on practicing my development skills through popular open-source projects, and by doing LeetCode and Codeforces. However, I'm afraid to take decision because of the current tech job market.
To all senior developers and engineers, I would appreciate your valuable advice. Please help me as if I were your younger brother!
Any advice appriceated.

Is there no more jobs for software engineers in market? Because the only thing I'm seeing is layoff, right now!

As a TV OS developer, I'm interested in enhancing the user experience by providing more granular control over applications. Specifically, I'd like to be able to:

Monitor the current state of an application, such as whether it's open, paused, or playing.

Interact with the application's UI elements, like buttons, menus, and sliders.

Control the application's media playback, including starting, pausing, stopping, and seeking.

Are there any existing APIs or frameworks within the TV OS ecosystem that would enable me to achieve these goals? If so, could you please provide more details on their capabilities and limitations?

Hey hackers,

Let's talk about the problem statement first!
In software engineering, engineers often procrastinate when it comes to writing comments for documentation purposes. As they delay properly documenting their codebase, they are even more likely to procrastinate on updating their previously written comments when they make changes to their functions or code. This can lead to chaotic and buggy code, and if not addressed, it completely obsolete or even counter intuitive the purpose of comments in the code.

Solution!
A tool that automatically detects changes in a function or code and compares them with the current comment description. If there is a discrepancy between the code and the comment, the tool either automatically updates the comment or allows the user to manually select the code and its associated comment to directly make changes using LLM's.

So, my question is: Is this idea worth working on? Is it a real problem, or am I just overthinking it? If anyone has a better idea, please share it in the comments. Also, if someone is working on this problem already or planning to work on this in future, we can collaborate. This will be an open-source project.

Sign out, Peace!
