PROFILE
Hariprasad Kelam
Harsha Kelam developed and enhanced Linux kernel network drivers in the geerlingguy/linux and torvalds/linux repositories, focusing on OcteonTX2 hardware. Over three months, Harsha delivered features such as MAC address synchronization, 48-bit DMA support, and XDP feature reporting, using C and deep knowledge of kernel development and embedded systems. The work included exposing firmware data via Debugfs for improved observability and implementing robust validation to prevent driver hangs and kernel panics. By refining device driver logic and network protocol handling, Harsha improved hardware compatibility, data-path reliability, and maintainability, demonstrating a strong grasp of low-level networking and driver development.
