Summary
🤩
RockstarMark Price is a seasoned software engineer and co-founder with 13 years of experience designing low-latency, high-throughput distributed systems and leading performance-focused teams. Based in London, he blends hands-on systems work—Linux tuning, JVM/Rust/eBPF development, and automated performance testing—with mentorship and operational observability to drive measurable latency and reliability gains. At LMAX he pushed end-to-end latency into the 100-microsecond range and taught system tuning techniques across engineering and operations. His open-source contributions to high-performance projects like OpenHFT’s Chronicle libraries and Aeron demonstrate deep expertise in native memory, thread affinity and durable replication. As an independent consultant and startup founder, he translates research-grade optimizations into production-ready systems and custom load-testing harnesses that deliver publishable KPIs. A practical polyglot, he often surfaces subtle resource-management and compatibility fixes that keep demanding systems stable under real-world load.
