Worked on the p4lang/p4c repository to deliver DPDK backend support for 128-bit constants, addressing previous limitations in handling larger immediate values for data-plane targets. The implementation involved updating dpdkArch.cpp and dpdkHelpers.cpp to correctly process and utilize 128-bit constants, thereby expanding backend capability and improving compatibility for DPDK-driven deployments. Demonstrated backend development and compiler engineering skills using C++ and the P4 language, with careful attention to backend architecture and code review discipline. No major bugs were fixed during this period, as the primary focus was on enhancing feature support and reliability within the DPDK backend.
