LeetCode
TiddlyWikiLeetCode is the best platform to help people practice solving coding problems and prepare for technical interviews. The main users are software engineers. LeetCode has over 1,900 questions covering many different programming concepts.

I loved it on the whole and felt very enthusiastic about using it store all my knowledge. It's super flexible and use of tags, filters and macros make it unique.

That's why I found "Obsidian", that's what I'm using today to store my knowledge.
