About this Gig
Need reliable firmware that works on real hardware, not just on a dev board?
I'm an embedded firmware developer with 4+ years of professional experience building production firmware for IoT products, EV AC chargers and medical devices.
What I can do:
- ESP32, STM32, AVR (ATmega328P), Nuvoton 8-bit MCUs
- BLE, WiFi, MQTT and cloud connectivity
- CAN, UART, SPI, I2C drivers and sensor integration
- FreeRTOS multitasking applications
- OTA firmware updates and custom bootloaders
- TFT display interfaces
- Debugging and fixing existing firmware
What you get:
- Clean, commented C/C++ source code
- Build/flash instructions and short documentation
- Tested on hardware
- Regular progress updates
Please message me before ordering with your MCU, requirements and deadline so I can confirm scope and timeline.
All code is written fresh for your project and the full rights are yours after delivery. NDA available on request.
FAQ
Do you need my hardware?
Not always. For common boards (ESP32, STM32 Nucleo, Arduino) I test on my own. For custom boards, you can ship a sample or we can test together remotely.
Which tools do you use?
ESP-IDF, Arduino, PlatformIO, STM32CubeIDE/HAL, Keil and Microchip Studio, depending on your project.
Can you fix or improve my existing code?
Yes. Share your code and describe the issue, and I'll review it and send a quote.
Who owns the code?
You do. Full rights transfer to you after delivery.
Do you sign an NDA?
Yes, I'm happy to sign an NDA before you share project details.
