Rockstar🎓
Top SchoolDaniel Mcardle is a software engineer with 12 years of experience specializing in networking, cryptography, and low-level systems work, currently contributing to QUIC at Google from Cambridge, MA. He has a strong open-source footprint, notably implementing Private Aggregation features in the Chromium mirror and adding HPKE support to the widely respected ring crypto library. His background spans embedded and tooling work—improving OpenTitan build and test flows and optimizing memory routines for constrained targets—alongside cloud storage tooling contributions to rclone. Comfortable across C/C++, Rust, and systems automation, he blends research-level cryptographic implementation with pragmatic engineering for production software. Equally at home teaching and mentoring, he’s combined academic roles and industry practice to ship secure, high-performance components used at scale.
