PROFILE

Ryan Everett

Worked on the zephyrproject-rtos/trusted-firmware-a repository, delivering security and reliability enhancements for embedded firmware. Focused on build systems and configuration management, the work included implementing flexible build-time generation of ROTPKs with support for multiple cryptographic algorithms such as RSA and P384, using C and Makefile. Addressed runtime stability by fixing buffer sizing for ECDSA verification and standardizing error handling in cryptographic modules. Upgraded project-wide security by enforcing MbedTLS version 3.6.2, refactoring configuration files, and updating documentation to mitigate vulnerabilities. Technical writing and documentation updates ensured clear developer guidance, supporting maintainability and consistent security across the codebase.
