Menlo Park, California, United States
Summary
👤
SeniorDomas Mituzas is a production engineer with 13 years of experience building highly efficient, user-facing data infrastructure at scale, currently focused on data performance at Facebook in Menlo Park. He specializes in optimizing “small data” workloads—many tiny, latency-sensitive interactions—spanning hardware, kernels, MySQL/InnoDB, caches and data access layers rather than analytics pipelines. His career includes keeping Wikipedia online through rapid growth, shaping Wikimedia governance, and deep roots in MySQL support and systems engineering from Sun and early internet-era projects in the Baltics. Known for pragmatic operational modesty and diagnosing performance issues end-to-end, he combines hands-on low-level expertise with a preference for real-time platforms that power billions of operations per second. An understated engineer, he balances broad systems knowledge with a clear focus on making everyday web interactions faster and more reliable.
