Summary
👤
Senior🎓
Top SchoolEvan Cheshire is a software engineer with 10 years of experience building high-performance compilers and systems for networking and ML hardware. A Stanford EE master’s graduate, he has driven backend compiler work at Barefoot Networks and currently optimizes latency and power on Apple’s Neural Engine through scheduling, resource allocation, and graph-level memory reduction. He blends low-level C/C++ expertise with higher-level Java and Python fluency to deliver practical optimizations that fit real silicon constraints. His open-source contributions to the P4 reference compiler improved type handling, determinism, and test coverage for the widely used Tofino backend, reflecting a focus on correctness and hardware-aware optimizations. Prior roles at Zoox and earlier internships show a history of shipping robust middleware and instrumentation tools for complex, safety- and performance-sensitive systems. Colleagues rely on him for deep systems thinking that translates into measurable latency, power, and throughput improvements.

Contributions summary:Evan primarily contributed to the P4_16 reference compiler, focusing on improving the type information handling for action selectors and profiles within the Tofino backend. They added annotations for counters with min/max width and implemented new test cases. The user also made several bug fixes and optimizations, including fixing a non-determinism issue in a switch profile and adding a bitvec barrel shift function. These changes indicate a focus on improving the compiler's functionality and test coverage.
