I build practical electronic products—from circuits and PCB prototypes to embedded firmware, control systems, and desktop tools for connected hardware.
Developing reliable firmware for STM32, ESP32, and AVR/Arduino platforms—from peripheral setup and device drivers to non-blocking application logic and persistent configuration.
Designing temperature and power-control firmware with PI/PID control, gain scheduling, anti-windup, derivative filtering, quiet-window ADC sampling, digital filters, and runtime safety supervision.
Working from schematic and circuit design through PCB layout, simulation, assembly, calibration, and prototype testing—including sensor front ends, heater drivers, relay protection, and power-control stages.
Integrating embedded devices with displays, storage, sensors, and diagnostic interfaces using I2C, UART/USART, USB CDC, external EEPROM, LCD modules, and Nextion HMI.
Building supporting software that connects users to hardware: desktop diagnostic tools, serial-port utilities, device interfaces, web applications, and lightweight automation.
Taking products through planning, prototyping, integration, validation, troubleshooting, and iterative improvement. Also experienced with CO₂ laser CNC operation, setup, optics alignment, basic maintenance, and production workflows.
