PROFILE
Kannan Suprayan
Worked on embedded systems and firmware development, focusing on memory management and security hardening in C. In the zephyrproject-rtos/trusted-firmware-m repository, addressed a critical memory safety issue by preventing out-of-bounds access in the RSE communication module, which improved robustness and reduced the risk of memory corruption in production. Later, contributed to tianocore/edk2 by implementing Non-Secure bit support in FFA_MEM_RETRIEVE_REQ, aligning with FF-A Memory Management Protocol v1.3 and enabling interoperability with Hafnium and other secure partition managers. Demonstrated expertise in low-level programming and system programming, delivering targeted improvements to core firmware reliability and standards compliance.
