Embedded Firmware Developer | ESP32, STM32, Raspberry Pi | C/C++, Python

Embedded developer with 5 years of experience. Freelancing since 2021.

I develop firmware and control software for electronic devices built around ESP32, STM32, Arduino and Raspberry Pi. My work connects the device layer with the operator interface and the services that collect and display its data.

I can help with:

• Embedded C/C++ firmware development and maintenance.

• Peripheral integration and debugging: sensors, displays, actuators, I2C, SPI and UART.

• Wi-Fi, Ethernet and LoRa communication, telemetry and device APIs.

• Web interfaces and touchscreen applications for connected equipment.

• Raspberry Pi applications, Python services, FastAPI and SQLite.

• Firmware troubleshooting, board bring-up support and deployment documentation.

Selected project experience includes Raspberry Pi coffee-machine control software, an ESP32 network-controlled audio device, a kinetic robot for film production, a camera-based inspection application, and a working wireless vibration-monitoring bench with on-device FFT analysis.

Tools and technologies: C/C++, Python, PlatformIO, ESP-IDF, Arduino, Raspberry Pi OS, FastAPI, SQLite, MQTT, WebSockets and hardware debugging.

Based in Krasnodar, Russia, available for remote project work. Please share your requirements, target hardware, schematics and existing code where applicable. We can agree on the scope, milestones, deliverables and acceptance tests. Hardware-dependent work requires a board sample or agreed access to a test bench.
