#About Me

Embedded Engineer & Hardware Designer

I am an Embedded Systems Engineer with 3+ years of experience across all stages of product design. I bridge the gap between complex hardware configurations and high-efficiency firmware architectures.

My experience spans RTOS device driver development, customized Embedded Linux Yocto builds, and multi-layer high-frequency PCB board designs. I focus on optimizing telemetry data integrity and local edge-computation to reduce cloud dependence.

#Interactive PCB Flow

Hardware-Firmware Integration Flow

1. Sensors & ADCs

SPI/I2C Analog Inputs

2. STM32 / ESP32 MCU

RTOS Core Processing

3. Storage Flash

Wear-leveling logs

4. Connectivity

MQTT / BLE Gateway

Analog & Digital Sensor Interface

I specialize in interfacing with high-accuracy industrial sensors. This involves configuring analog-to-digital converters (ADC) and low-noise operational amplifiers, along with robust serial buses (I2C, SPI) to pull real-time telemetry like voltage, current, power factor, and ambient temperatures.
