Rockstar🎓
Top SchoolAlexandra Voinea is an embedded software developer with 10 years of experience specializing in firmware for 3D printers and deep expertise in C/C++, AVR and ARM assembly, Python, and hardware validation. She designed key firmware for Prusa products including the MK2/MK3 families and authored the MMU3 bootloader, while contributing low-level STM32 fixes and new-family support to the widely used Klipper 3D-printer firmware. Comfortable leading cross-functional efforts, she applies Scrum, CI-driven testing, simulation and strict coding standards to ship safe, reliable firmware and to rapidly mitigate supply-chain-driven component substitutions. Her background in electronics design, PCB layout, prototyping and IT/network infrastructure complements her firmware work and helps bridge hardware-software integration. A proven educator and team builder from her robotics roots, she brings strong communication and inclusive leadership to collaborative engineering teams.

Contributions summary:Alexandra primarily contributed to the low-level firmware aspects of the Klipper 3D printer firmware, focusing on STM32 microcontrollers. Their work involved fixing issues related to USART communication, specifically addressing overrun flag handling on specific STM32 families. Further contributions included preventing accidental disabling of the SWD interface, adding support for the STM32G0B0 family, and configuring microstep lookup tables for TMC drivers. This indicates a strong understanding of STM32 hardware and firmware development.
