Summary
👤
Senior🎓
Top SchoolMarcus Holland-moritz is a seasoned freelance consultant and engineer with over two decades of production experience across embedded systems, large-scale distributed services, and performance-critical C/C++ codebases. He helped design and ship search and spell-correction infrastructure at Facebook that handled tens of billions of queries per day and materially improved memory use, latency and internationalization across 100+ languages. A former Perl core developer and CPAN author, he still maintains modules used in core Perl and built a highly-regarded read-only compressed filesystem project on GitHub. Marcus is an expert in performance analysis and debugging tools (gdb, asan/tsan/ubsan, perf, valgrind, jemalloc) and frequently mentors, reviews code, and interviews engineering talent. Comfortable moving between firmware, hardware design and cloud-scale services, he thrives on sharing deep systems knowledge while tackling new, practical challenges.
