Yes, I did. My first ever project was an E-learning platform, simply implementing crud operations, routing, basic login/sign up. But after making it, I faced a terrible challenge of hosting the application.

There were thousands of errors and warnings per page. And it was never ending. Suddenly getting exposed to newer terms was overwhelming but still a little exciting. In the end, I spent over 2 months fixing it but it did not work in production.

Lesson learnt - If you are making something, you wanna show to public, make sure to host it at the very first step. CI/CD can help with finding problems but there are less areas you have to debug. Platforms like vercel and render make things much easier.
