You will get Embedded Firmware + IoT Backend | ESP32, STM32, Raspberry Pi
Project details
I will build embedded systems that handle edge cases and are maintainable long-term.
I work primarily with the ESP32 family (ESP32, ESP32-S3, ESP32-C3), Arduino, STM32, and Raspberry Pi, and I'm comfortable across the full stack: low-level peripheral configuration, wireless protocols (BLE via NimBLE, Wi-Fi), sensor integration, data logging, and display interfaces. I have hands-on experience with I2C, SPI, UART, and MODBUS for industrial and commercial applications.
Beyond the device itself, I develop the backend infrastructure to support IoT deployments—REST APIs and databases for logging sensor data like temperature, speed, and operational variables, giving you visibility into your devices from anywhere.
What you'll get:
• Clean, well-documented firmware tailored to your requirements
• Schematics and hardware documentation
• Clear technical documentation for future maintenance
• Ongoing support and iterative upgrades on demand
Recent projects include wireless sensor nodes, touch-controlled embedded UIs, and end-to-end systems with SD card logging and cloud connectivity.
Send me a message with your project details and I'll let you know how I can help.
