About

How I think about building hardware that actually ships.

I'm an embedded systems and product design engineer who enjoys owning the full stack of a hardware product—from the first block diagram to the final enclosure on someone's desk.

On the electronics side, I work on mixed‑signal PCBs, power stages, and microcontroller‑based systems. I care about layout discipline, signal integrity, and designing boards that are easy to test, debug, and scale into production.

On the firmware side, I write C/C++ for MCUs, build real‑time control logic, and integrate connectivity for IoT devices. I like firmware that is predictable, well‑structured, and documented enough that another engineer can pick it up quickly.

For mechanical design, I model enclosures and assemblies that respect real‑world constraints: tolerances, fasteners, cable routing, and how a technician will actually assemble or service the device.

What I bring

  • End‑to‑end hardware product development
  • Mixed‑signal PCB and power design
  • Firmware for real‑time and IoT systems
  • Mechanical design for enclosures and assemblies

Tools I use

KiCad / EasyEDA / Altium ESP‑IDF Arduino IDE C / C++ VS Code STM32Cube SolidWorks Blender Git / GitHub
