🧠 About Me

⚡ Firmware Engineer at Abbott developing safety-critical bare-metal C firmware for implantable cardiac devices on ARM Cortex-M. My work spans register-level peripheral drivers, low-power sequencing, and hardware bring-up across embedded platforms.

🔧 Outside of work I build on the Arty Z7 (Zynq-7000), focusing on AXI peripheral validation, custom bootloaders, and hardware-in-the-loop test automation.
