I work in embedded development, working with MCUs, MPUs, and other IoT related products. In summary, I work right on the interface between hardware and software, developing device drivers.
I have a personal GitHub where I host all of my auxillary projects. This helps me stay up-to-date with GitHub and its newest features, as well as a place to share the projects I find interesting on my free time.
To keep in line with the Feynman Technique, I am attempting to keep a blog of my coding techniques not only to share my thoughts, but to refine the concepts for myself. Technical writing is imparative for me to digest the code I absorb each day - whether it be from text books or StackOverflow - and retain it.
