He’s comfortable across the stack from low-level packet processing (DPDK, PF_RING) to configuration management (Chef, Puppet) and has a track record of fixing brittle builds and test pipelines. Colleagues would note his pragmatic focus on reliability and measurable improvements to production tooling that often live behind the scenes.
