Hello guys 👋

If you watched my MongoDB course and want videos on any other topics, definitely comment below 🙌

I’m planning to create a “100 MongoDB Questions” series covering:

* Basic to advanced MongoDB questions
* Complex aggregation pipelines
* Advanced queries
* Real-world problem solving
* Interview-style questions

I’m also planning a separate video on Vector Search using MongoDB 🚀

If you’re interested in these topics, do comment — your support and suggestions really motivate me to continue this series in more depth ❤️

Also, if there’s any other topic you want me to cover, feel free to suggest it anytime. I’m always open to suggestions 😊
