I am an AOSP BSP porting and embedded Linux specialist. I have years of bare-metal and RTOS firmware experience for 8-bit MCUs through ARM9. My focus areas include bring-up, debugging, kernel, drivers...

About this Gig

Are you looking for an experienced embedded firmware engineer? With 27+ years of hands-on experience, I deliver production-ready firmware and BSP solutions for a wide range of platforms.

What I offer:

Android BSP bring-up (AOSP 10-14) on Rockchip, Qualcomm, and MediaTek SoCs
MCU firmware development: STM32, ESP32, nRF52, 8051, PIC, AVR, MSP430
FPGA development in Verilog (Altera Cyclone III, Efinix Trion)
Linux kernel porting, Device Tree customization, and HAL development
Communication protocols: RS-485, CAN, SPI, I2C, USB, BLE, WiFi, MQTT
OTA update systems with secure boot, A/B partition, and rollback
Motor control: BLDC, stepper, PID, PWM
Hardware debugging with oscilloscope, logic analyzer, JTAG/SWD

Why work with me:

15+ production-deployed projects including 10,000+ unit factory deployments
Full-stack embedded: from bootloader through kernel to application layer
Clear documentation and build instructions delivered with every project
CTS/VTS compliance experience for Android devices

I bring systematic methodology: bootloader first, then kernel, then HAL each layer verified before moving to the next. Let's discuss your project requirements.
