Rohanth P.

I am a Senior Hardware Design and Embedded Systems Engineer with 6+ years of experience in end-to-end hardware development, high-speed PCB design, embedded computing platforms, and product engineering.

My expertise covers the complete hardware development lifecycle — from system architecture and component selection to schematic design, multilayer PCB layout, hardware bring-up, debugging, and validation.

I have hands-on experience developing advanced embedded computing platforms, including NVIDIA Jetson System-on-Module (SoM) carrier boards, Raspberry Pi Compute Module carrier boards, SMARC-based embedded platforms, and Xilinx FPGA-based hardware designs, including high-speed DDR memory routing.
