Hi Huy,

Another related issue that arises if you wait to push all of your new code at once is that your PRs become very large and more complex to review. So in addition to publishing your code early and often, I would also encourage you to divide your tasks into smaller units that can be easily debugged, tested and reviewed. Creating separate specific issues on Github for each small task might be a good way of keeping track of what work is in progress, what you still need to do, and what you've finished.
Best, Marcela
