Summary
👤
Senior🎓
Top SchoolAndrew Ong is a Senior Firmware Engineer with 14 years of embedded systems experience, currently focused on medical and wearable devices in the San Francisco Bay Area. He has deep hands-on expertise with ARM Cortex M4/nRF52 platforms, low-level C firmware, schematics, RF (BLE/Wi‑Fi), and peripherals like SPI/I2C/UART, plus a knack for decoding obscure silicon errata. At Meta he led Wi‑Fi latency and lab automation for AR glasses, building Python hardware-in-the-loop tests and remote flashing infrastructure that directly enabled battery and antenna optimizations. Previously he extended a children’s wearable battery life twelve-fold and implemented authenticated BLE with bonding and private addressing, showing both product sensibility and security awareness. Comfortable across PCB layout (Altium), oscilloscope automation, and scripting (Python/Bash), he documents projects on his technical blog and thrives in contract-manufacturing environments with end-to-end production experience. A practical problem-solver, he combines low-level bit-twiddling fluency with systems thinking to deliver reliable, field-tested firmware.
