Senior🎓
Top SchoolDavid Lam is a software engineer with 12 years of experience building and operating large-scale search infrastructure at Facebook, currently on the IndexServe team in San Francisco. He has deep backend expertise in distributed systems and storage, evidenced by contributions to Facebook's LogDevice repository where he extended core components and implemented tooling like the data-size ldshell subcommand. Prior roles span production engineering, performance-focused internships at IBM (including an 84% CPU reduction in a DB2 transport prototype), and hands-on QA and teaching experience—showing a blend of systems-level optimization, testing rigor, and mentorship. Comfortable across C, Perl, Bash, Ruby, and large codebases, he pairs pragmatic engineering with an eye for maintainability and correctness. Collected academic roots in computer science and area studies from Dartmouth underpin his pragmatic, systems-first approach to problem solving. He brings both product-focused production engineering sensibilities and open-source contributions to complex distributed storage projects.
