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

Projects

Selected work that reflects my approach to embedded systems and product design.

Embedded audio capture system PCB

Embedded Audio System

Embedded Audio

ESP32‑S3 based system with digital I2S microphone capture and Class D amplifier playback. Audio stored on microSD in standard WAV format.

  • One‑Button Recording — Press START to record, STOP to finish
  • Instant Playback — Play last recorded audio with a single button press
  • Auto File Numbering — Sequential naming (rec_1.wav, rec_2.wav…)
  • Up to 60s Recording — Configurable maximum per file
  • Auto Power Switching — Seamless USB ↔ LiPo battery handoff
  • Smart Amplifier Control — Auto power‑down when idle (saves battery)
ESP32‑S3 • I2S • KiCad Signal integrity • Power design
AI Timer system PCB
