Senior🎓
Top SchoolWenjin Zhang is a senior firmware engineer with 11+ years building low-level drivers, bootloaders and communication stacks across ARM, x86 and PowerPC platforms for embedded, printer and IoT products. He has deep, practical expertise in STM32 and RF51822 ecosystems—contributing device support and flash/debug integrations to the popular pyOCD open-source project and maintaining DAP-Link/OpenOCD toolchains. His work spans real-time OS ports (ThreadX, VxWorks), robust FOTA and Meshtalk networking, custom bootloaders and security/DTLS libraries, reflecting a full lifecycle embedded mindset from startup code to production firmware. Comfortable across C/C++, assembly and scripting, he pairs decades of legacy Windows/embedded driver experience with modern MCU toolchains and JTAG trace tooling. Based in Shanghai, he brings a blend of standards-driven process familiarity (CMMI5) and hands-on problem solving that surfaces in complex hardware-software integration projects.
