Summary
🤩
Rockstar🎓
Top SchoolKamil Tomaszewski is a Developer Program Engineer based in Malmö with 7 years of experience specializing in embedded systems and IoT. He builds and debugs low-level USB and board-support code, contributing to high-profile open-source projects like TinyUSB and Adafruit's CircuitPython to improve MSC, HID, and endpoint handling. At Sony (since 2019) and previously at Tieto, he has delivered platform-specific initialization, interrupt handling, and USB device-controller fixes for real hardware such as the Spresense/CXD56. Trained in Automation and Robotics (MSc) from Wroclaw University of Science and Technology, he combines robotics fundamentals with practical firmware expertise. Notably, his open-source work demonstrates attention to subtle hardware quirks—adjusting packet sizes and endpoint numbering to make USB stacks behave reliably across diverse microcontrollers. He brings a pragmatic, hardware-first mindset to developer-facing engineering and platform enablement.
