Summary
🤩
Rockstar🎓
Top SchoolAlun Evans is a Senior Staff Software Engineer based in the San Francisco Bay Area with 13 years of experience building high-performance, infrastructure-level systems that enable developer productivity. He has deep expertise across networking, routing, and kernel-adjacent technologies—shipping production code at Cisco and leading service discovery, routing, and eBPF work at Uber. Alun combines low-level C and systems thinking (lock-free coding, shared memory, kernel drivers) with modern Go-based cloud infrastructure, contributing performance improvements to the widely used cilium/ebpf Go library. He is comfortable both as an individual contributor and as a leader of distributed teams, and has taught on-call practices broadly across an organization. Known for finding and fixing inefficiencies from architecture down to micro-optimizations, he also periodically resets his perspective—once spending a sabbatical solving >100 LeetCode problems and deep-diving into distributed systems literature. Trained at the University of Manchester, he pairs rigorous engineering craftsmanship with a pragmatic focus on scalable, observable systems.

Contributions summary:Alun primarily contributed to the `ebpf-go` library, focusing on enhancing the eBPF functionality. Their work included fixing typos, exporting and using the `PossibleCPU` to allow pre-allocating per-CPU slices, and enabling pre-allocation in per-CPU maps. The user also implemented support for batch APIs on per-CPU maps, offering performance improvements, and made examples testable by generating stable output.
