Winmic Electronic Design LLC — Managing Member

July 2020 – Present Chapel Hill, NC

Founded a contract electronics design consultancy specializing in high-voltage systems, microcontroller-based power supplies, and embedded control for industrial, medical, and consumer applications. Selected accomplishments:

● High Voltage Power Supplies: Designed multiple capacitor discharge power supplies up to 32 kV for applications including cable fault thumpers (Megger Inc.), Xe-lamp drivers for optical scanners and water purification, and wearable electrostatic pathogen neutralization systems.

● Embedded Systems & Firmware: Developed microcontroller-based high-voltage pulse generators using PIC, Atmel/Arduino, ARM Cortex, and ESP32 platforms with control over duty cycle, pulse duration, and current regulation. Interfaced with SPI, I C, UART, analog, 4–20 mA, LoRa, Wi-Fi, Bluetooth, and RFID systems.

● Product Development: Designed and prototyped the full electronics system for:

BravoWalk: A leash-mounted training aid delivering a timed shock (up to 1.5 kV) with programmable logic and warning stages.

Henley Ion Mask: High-voltage electrostatic air purifier for healthcare workers (-12 kV output, LiPo battery-powered, MCU-controlled).

Aura Ion Bar: Negative ion generator with MCU-controlled voltage (-3 to -12 kV) and variable-speed BLDC fan for ion distribution.

● Ozone System Design: Engineered medical-grade ozone generators using high-voltage output from oxygen input, with integrated pressure sensors, gas flow control, SPI DAC/ADC, and display systems.

● Tools & Capabilities: Expert Altium Designer user with fully equipped home lab (signal generator, 40 kV meters, reflow oven, etc.), enabling rapid prototyping and validation. Zoetis LLC 10/2021 – 07/2025
