Professional Electrical Engineering Design Services

I specialize in delivering innovative electrical engineering solutions with expertise in a broad range of microcontroller families, including ESP32, PIC, STM32, MSP430, ATMEL/Arduino, and ARM Cortex. My extensive experience includes interfacing with diverse sensors using analog, digital, UART, SPI, I2C, 4-20mA, LoRa, Wi-Fi, Bluetooth, RFID, USB, and RS-485 protocols.

As an Altium license holder and expert user, I excel in PCB design and layout for complex electronic systems. I take pride in developing new products, embracing the challenges of design and prototyping with enthusiasm. My home lab is equipped with advanced tools, including a signal generator, oscilloscope, high-voltage meters (up to 40kV), soldering station, and reflow oven, enabling me to design and build both electrical and mechanical prototypes tailored to various markets.

Notable Projects

Bravo Walk Dog Collar

I designed the high-voltage power supply, LiPo interface, magnetic sensors, and visible/audible feedback system for the Bravo Walk Dog Collar. This innovative device delivers TENS voltage stimulation to a leashed animal after pre-defined firmware-controlled warnings (audio and vibration) if the leash is pulled for a set duration. The circuit provides a compliance voltage of up to 1.5 kVDC, adjusted to lower levels for final application. Learn more

High-Voltage Shocking Wallet Module

I developed a BLE-controlled high-voltage wallet module utilizing a Seeed Studio XIAO microcontroller with Arduino IDE. The module included:

• Variable high-voltage pulse (300–2,500V) triggered by unauthorized wallet removal.

• 1S LiPo battery with USB recharge capability.

• Ambient light/PIR sensors and NFC technology.

Ozone Generation Electronics for Medical Applications

I designed electronics to generate ozone (O3) from medical-grade oxygen (O2) for medical use, incorporating:

• High-voltage power supply (up to 20 KVAC).

• Pressure transducers, O2 flow control, and valve/pump control.

• LCD displays, SPI-based ADC/DAC integration. Learn more

Pathogen-Neutralizing Medical Mask

I contributed to the early-stage development of electronics for a medical mask designed to purify incoming air and neutralize airborne pathogens via electrostatic precipitation. My responsibilities included:

• High-voltage generation (-12 KV, 200μA).

• Microcontroller selection and programming.

• LiPo battery management and LED control. Learn more

Negative Ion Generator with Variable High Voltage

I developed the electronics for a negative ion generator featuring:

• ESP32 microcontroller (Arduino IDE).

• Variable high-voltage output (-3 to -12 KV).

• BLDC motor for ion distribution. Learn more

Restroom Hygiene Innovation

I recently filed a provisional patent for a product designed to enhance hand sanitation during restroom use via cold plasma ionization. This product utilizes a custom high-voltage supply (-3 to -12 KV) entirely designed by me and is currently in the MVP stage. Learn more
