Brice Halder is a software engineer with a decade of experience and 3+ years at Meta driving large-scale performance optimizations, developer tooling improvements, and platform migrations that improved latency, cold start times, and build speeds for thousands of engineers. He combines deep systems-level experience (C++, React Native, Python/Starlark) with a knack for developer experience, having led cross-org migrations to ARM Macs and clang upgrades while reducing build and telemetry overhead. At Meta he repeatedly shipped high-impact fixes—boosting send throughput, cutting Windows startup by 10s, and preventing multiple release failures through hands-on oncall leadership. Now at Snap, he continues to focus on native messaging and performance-sensitive systems. Outside work he automates tasks with scripts and maintains a popular side project, Wikipedia Speedruns, reflecting an unusual mix of production-scale engineering and playful, user-facing web development.
