Hi, I’m Errol.
I’m an Embedded Firmware Engineer working on cryptographic subsystems for ARM microcontrollers – porting drivers, building demo applications, validating crypto APIs, and keeping codebases clean through static analysis and compliance work.
Professionally, I spend my time at the boundary between hardware and firmware: mapping registers, debugging integration issues, running test vector suites, and making sure crypto implementations actually work correctly on real silicon. I also build Python tooling that makes repetitive workflows faster for my team.
This site is a quick overview of what I work on and how I work.
