Senior🎓
Top SchoolOndrej Lehecka is a software engineer with 11+ years building high-performance, large-scale distributed systems and infrastructure across Meta, LinkedIn, Microsoft, and Tesla. He has led architecture and implementation of critical storage and RPC systems—operating one of the world’s largest HDFS clusters and contributing to Facebook’s Thrift and RSocket integrations—while repeatedly removing scaling bottlenecks in production. Equally comfortable as an individual contributor and technical leader, he drives design, debugs complex performance issues, and mentors teams to deliver robust, low-latency services. His open-source work on fbthrift and structured concurrency C++ libraries reflects a deep focus on async and concurrent systems. Based in Mountain View, he combines rigorous academic training toward a PhD with hands-on experience in real-time media, networking, and autonomous vehicle teleop. Colleagues know him for tackling the gnarly infrastructure problems others avoid and turning them into dependable platforms.
