Summary
🤩
Rockstar🎓
Top SchoolDaniel Degrasse is a Senior Firmware Engineer with eight years of embedded systems experience, currently supporting product firmware at Tenstorrent from Austin, Texas. He is a top contributor and maintainer in the Zephyr RTOS community, having architected and implemented the SD/SDIO subsystem and drivers for multiple SoCs while improving display, flash, and peripheral stacks. His expertise spans disk/flash technology, embedded display pipelines, TCP/IP networking, and low-level driver development (UART, SPI, I2C, I2S), with hands-on experience enabling multicore SoCs and SOC-level power management. Previously at NXP he drove upstream enablement and tooling that accelerated new product integrations and customer wins. Comfortable across firmware, bootloaders (MCUBoot), and full-stack tooling, he blends deep systems-level knowledge with a collaborative open-source mindset. An uncommon strength: he balances large-scale upstream stewardship with pragmatic device bring-up experience that shortens time-to-production.
