Sunil Velagapudi developed and refined RISC-V platform boot and payload infrastructure in the NVIDIA/edk2-platforms repository, focusing on UEFI firmware and embedded systems. He implemented a standardized boot process supporting both PEI and PEIless flows, introduced dynamic ACPI and Device Tree integration, and enabled RAMDisk booting for storage-constrained environments. Using C, Assembly, and Makefile, Sunil reduced code duplication through shared DSC/FDF includes and streamlined platform configuration. His work included payload boot design for SiFive U5 and U540, codebase cleanup, and repository management. The engineering demonstrated depth in system initialization, maintainability, and cross-platform scalability for RISC-V firmware development.
