Summary
🤩
RockstarBiqu And Bigtreetech Company is an experienced embedded systems and IoT engineer based in Shenzhen with eight years working at BIGTREETECH, a leading 3D printer hardware and accessory manufacturer. They specialize in firmware development and hardware bring-up for 3D printer control boards and touchscreens, contributing significant Marlin and Klipper patches that address ADC/USB/SPI issues, power-loss recovery, and multi-board support. Their work spans low-level STM32 HAL fixes, bootloader improvements, and full-stack touchscreen UI features, including multilingual support and usability enhancements. Combining hands-on firmware troubleshooting with knowledge of international product certification and global supply chains, they bridge engineering and product readiness for markets like the US, Korea, and South Africa. A less obvious strength is their iterative maintenance of firmware across multiple board revisions (e.g., SKR-mini-E3 V3.0 and Octopus V1.0), which demonstrates skill in long-term support and backward-compatible development.
