Personal · mini UART @ 115200

Bare-metal AArch64 firmware for a Raspberry Pi 3B — custom boot, then AUX mini UART TX on GPIO 14 with no OS.

Work-in-progress C model of part of RV32I — not yet able to run compiled code or riscv-tests.

92% held-out · ~80 µs inference

A real-time voice-activation engine built in bare-metal C that captures audio and runs machine learning inference directly on an STM32 microcontroller.

3 → under 1 LSB noise

A battery-powered dual-axis light tracker in bare-metal C on an ATmega328P with MOSFET H-bridges and a fixed-point Kalman filter.

6× DC resolution · 2× voltmeter precision

A Raspberry Pi-based digital multimeter and function generator featuring custom analog front-ends, a software-driven SAR ADC, and a 4-layer mixed-signal PCB.

Personal ESP32 and Arduino projects I worked on before.
