My personal projects have always covered the areas software engineering that didn't get to touch in my professional experience.

For example I first learned React exclusively through my own projects to fill a hole in my knowledge (and because they internet told me it was better than Angular).
This has also led me to learn React Native as a better way of making mobile apps from my Android Java origins.

Finally my interest in meta-frameworks and what is at the forefront of web development persuaded to make this website with the AHA stack.
