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!
