Project details
Need a reliable developer for your embedded systems project? I specialize in firmware development and RTOS integration for both simple and advanced microcontroller-based systems. I work with 32-bit MCUs like STM32 and ESP32, as well as 8-bit controllers including Arduino and PIC microcontrollers from Microchip. I also develop on microcomputers like Raspberry Pi and BeagleBone.
I’m proficient in industry-standard tools and frameworks, including STM32CubeIDE, ESP-IDF, Espressif Studio, Arduino IDE, and MPLAB X IDE, ensuring clean, maintainable code across platforms.
From sensor interfacing and GPIO control to RTOS-based multitasking systems, I can deliver scalable and robust solutions tailored to your specific application. I support popular communication protocols like UART, SPI, I2C, MQTT, Wi-Fi, and Bluetooth, and provide full-stack integration with cloud and local systems.
Let’s bring your embedded idea to life—on time, efficiently, and with technical precision.

PCB Design Review for Two Small Boards
Working with Bonface was an absolute pleasure. He was highly professional throughout the project, responded promptly to all communications, and demonstrated an exceptional work ethic. I found him to be trustworthy, reliable, and consistently punctual, which was greatly appreciated.
Bonface went above and beyond my expectations to ensure the project's success, and the quality of his work was outstanding. I would not hesitate to hire him again and would highly recommend him to others.
Thank you, Bonface, for your excellent work.

Help Needed to Debug Custom ESP32-Based PCB (Live Video Support)
Bonface has taken my messy wires design and converted it into a fuly functioning PCB design.
We have gone through 5 or 6 iterations before finally reaching the end working product which included an ESP32-S3 which controlled a servo motor temperature sensors, current draw sensor, load power cutoff through gpio control.
And everything was battery powered using a 3S lipo battery.
I made many iterations but Bonface took them and made a better design each time within 3 days.
