Introduction

Thank you for looking my profile.

I’m embedded firmware and software developer over 7+ experiences. I’m worked over multiple position before full-time and full-stack developement embedded device: Hardware development (PCB layout, Schematic design), Software development (Windows, Linux), Mobile application development (Android, iOS). And I’m also worked on almost process of products development from prototype to production process.

I build small home labs has some tools and equipment support for developing, testing and debugging embedded devices. I have a team include firmware/software (me), hardware, and mechanical engineering for fully support embedded device development.

My experiences and skills:

• Embedded firmware and software development C/C++.
• Embedded GUI: LVGL, TouchGFX, GUIx, UI design and deploy.
• Embedded WebServer: Bootstrap, Javascript, html, mobile and desktop view scalable especial lightweight and performance.
• Desktop application: Windows, Linux (Python, C#).
• Mobile application: Android, iOS (Xamarin, .NET MAUI), launch to AppStore and PlayStore.
• Iot Cloud: AWS Iot, Azure Iot Core, Thingsboard Cloud.
• Connectivity: BLE, WIFI, ETH, NFC, CAN, MODBUS, USB (WINUSB, WINCID, LIBUSB, etc.), Z-WAVE etc.
• Real-time operation: freeRTOS, Azure RTOS(Threadx), Zephyr, etc.
• Microcontroller: STM32, EFR32, EFM32, ZGM23, NRF52, ESP32, PIC, AVR, ATSAM, Ambiq Apollo, etc.
• Embedded Framework: STM32Cube, nRF Connect, nRF52 SDK, Zephyr, ESP-IDF, SiliconLabs Gecko, etc.
• Device firmware update(DFU): OTA, Bootloader, Secureboot, Flash encryption, etc.
• Manufacturing: ATS(Automation Test Software), testing firmware, flashing tools and scripts, Secureboot, Flash encryption, etc.
• Low power consumption.
• Troubleshooting and bug fixing.

Debugging:

• JTAG, SWD, ST-LINK, J-LINK, etc.
• Segger Ozone, Open OCD, etc.
• IDE: Visual Studio, Visual Studio Code, Simplicity Studio, STM32CubeIDE, Segger Embedded Studio, Eclipse.

Feel free message to me for discuss your project.
