Rockstar🎓
Top SchoolRyan Mcclelland is a firmware engineer with 11 years of experience designing low-level software for microcontrollers and DSPs, currently developing unannounced prototypes at Reality Labs Research (Meta). He brings deep C and ARM assembly expertise, a strong track record building UART/I2C drivers, USB stacks (DFU and CDC), and low-latency serial communication for embedded products spanning consumer wearables to transit hardware. Ryan has shipped safety-critical and production systems for automotive and mass-transit customers, and has experience with embedded Linux, Yocto kernel builds, and hardware bring-up. He combines systems-level debugging and toolchain management—Jenkins, GitHub, JIRA, Confluence—with hands-on driver and ISR development. Uncommonly for a firmware engineer, he has also created desktop tooling (C# GUI test tools) and taught Git internally, reflecting an ability to bridge embedded constraints with developer workflows.
