Hey! I’m Rafael — a firmware engineer focused on embedded systems, IoT, and low-power devices.
I enjoy digging into registers, optimizing code for power efficiency, and making hardware and software work seamlessly together.
Outside of work, I like experimenting with embedded ML, debugging boards, and automating small hardware tools.
🎓 I also completed the Global Summer Institute (Big Data & AI) at UT Austin, where I worked on applied ML projects and earned top marks in Python and AI modules.
