Selected work

QuestOS

Implemented a UEFI Graphics Output Protocol driver and a full virtual console for QuestOS, Boston University’s research RTOS, allowing the Quest shell to render directly to the framebuffer. Extended the Quest-V partitioning hypervisor with custom hypercalls and EPT mappings, integrating framebuffer handoff with QuestOS’s physical and virtual memory managers so display output remains coherent across sandbox switches.
