About Me
I build across the hardware/software line — PCB design and firmware for embedded systems, plus CLI tools, desktop apps, and AI experiments.
The interesting problems live at the intersections: deploying ML on microcontrollers, building developer tools that read your git history, or designing a USB-C power analyzer from scratch.
