Hardware Development
I am involved in both hardware and software development. I have more than 10 years of experience in this field, especially in the design and development of embedded systems and IoT (Internet of Things) devices. I enjoy challenges that require unconventional solutions, and I thrive on finding solutions that address unique problems and situations.
Professional Background
My passion for electronics and programming began in my youth, and I first encountered microcontrollers and sensors in the 1990s. Since then, I have continuously developed my knowledge and skills to use the latest technologies and tools in my work. I completed my studies at the Szigeti Gyorgy Technical School, where I graduated as an electronics and IT technician.
Hardware Development
In the field of hardware development, I primarily focus on designing embedded systems. The devices I design include various IoT sensors and actuator devices that can be used in a wide range of industries. I use Autodesk Eagle and Fusion 360 software in the design process. With Eagle, I create precise and reliable circuit designs, while Fusion 360 allows me to create 3D models that aid in the production and testing of prototypes.

Regulated Overvoltage Protection
Custom-developed grid overvoltage protector designed for solar panel systems. Development: 2022–2025.
- V1: 2-step regulation (10V + 20V)
- V2: 1×10V step fine regulation
- 3 prototypes: 1× 3×63A, 2× 16A (single phase + 3-phase)
- Patent application submitted to SZTNH (Hungarian Intellectual Property Office)
Ensures the longevity of protected-side equipment while allowing own solar panels to feed back into the protected network.
Camera Grip for Motorcycle Touring
Raspberry Pi Zero + Logitech C920 based action camera grip, designed for documenting motorcycle tours. Custom 3D-printed enclosure.
Industrial Automation
Development of various actuator devices for production line automation. PCB design, current transformer (CT) selection for 100A+ loads, sub-metering system design experience.
Embedded Systems
In addition to hardware development, I am also involved in software development to optimize and control the operation of the designed devices. My experience extends to writing embedded software, programming various microcontroller platforms, and establishing network communication for IoT devices.
