I enjoy writing software that solves a well defined problem with a nice API, usually in Go. I’m one of the maintainers of cilium/ebpf, a widely-used interface to Linux’s eBPF subsystem.
In the past I have worked on Cloudflare’s global L4 load-balancer Unimog and a globally replicated key-value store called Quicksilver.
