Embedded Systems Engineer · Electronics & Firmware Developer · Technology Product Developer

I build complete technology products where electronics, firmware and software work together as one system.

My experience covers the full development cycle — from microcontrollers, electronics and custom controllers to firmware, communication protocols, backend systems, APIs and web interfaces.

I work with embedded platforms including ESP32, STM32 and AVR, as well as the Arduino Framework, serial communication, RFID, payment systems and custom electronic devices.

What I Do

  • Embedded systems and firmware development
  • Electronics and custom controller design
  • ESP32 / STM32 / AVR
  • Arduino Framework
  • UART / RS-485 communication
  • RFID and payment-system integration
  • Displays and control panels
  • OTA firmware updates
  • Backend and API development
  • Docker / Docker Compose
  • MongoDB
  • Web-based management systems
  • Hardware/software integration
  • Product development and technical support

WASH-PRO

I am the Founder and Lead Architect of WASH-PRO TECH Global.

WASH-PRO is a hardware and software platform for self-service car washes. I developed the product ecosystem around the equipment, including custom controllers, embedded firmware, displays, communication protocols, payment and RFID integration, backend services and management software.

The project represents my approach to engineering: the software is not an isolated product — it is part of a complete physical system that has to work reliably in the real world.

Open Source & Legacy Projects

I am gradually publishing parts of my previous work and older code in public repositories.

Some of these projects represent earlier stages of my engineering experience and may use technologies or approaches that differ from my current stack. I keep them available as a technical record of my development path and experience.

Engineering Focus

Fault tolerance · Reliability · Energy efficiency · Hardware/Software Integration · Embedded Systems · IoT · Product Development

I am open to technical discussions, expert consultations and engineering collaborations related to embedded systems, electronics and adjacent technologies.
