Huy Le

Welcome to my blog!

Here, you’ll find posts on lessons I’ve learned, the things I find interesting, and what I am working on. Although I am not much of a writer, (really, it takes me a very long time to write together a post), it is an attempt to track my thoughts and share learnings through the years.

Although my interest is wide, you will most likely find contents regarding **software** and **hardware development** on this blog.

Feel free to scan around! If there is anything that may interest you, or if you have any questions, please feel free to reach out to me!

Wanna know more about me? Find out a little more here.
