As a specialist in electronics and software, I have extensive experience with embedded systems, microcontroller programming and real-time communication protocols. Over the years I have worked with STM32 (ARM Cortex-M), Arduino (AVR), ESP and other microcontrollers, making effective use of protocols such as UART, SPI, I²C, RS-485, CAN Bus.

On the web and backend side, I build modern frontends with Next.js and React, and architect complex systems on Node.js. For data management I use PostgreSQL and MongoDB, and for content and e-commerce I rely on Strapi and Medusa.js. For object storage I use MinIO, and for real-time communication I use MQTT and WebSocket.

On the hardware side I design professional PCB layouts in Altium Designer, KiCad and EasyEDA, and simulate circuits in Proteus and Multisim. On Raspberry Pi, Orange Pi and Armbian Linux systems I make extensive use of Python for device configuration and GPIO control, and I manufacture mechanical parts with 3D printing.

On the mobile side I develop apps in Kotlin and Flutter that read data from and control Arduino and other sensor-based systems. I also have hands-on experience in a specialised engineering project on Underwater Robotics (ROV) systems and the assembly of 18650 Li-ion battery packs (6s2p, 6s3p) together with BMS integration.

As a trainer who enjoys sharing knowledge and experience, I prepare teaching materials on digital electronics, C programming and microcontrollers, and contribute to training specialists in this field.
