Rockstar🎓
Top SchoolDaniel Peebles is a seasoned programmer with 18 years of experience applying formal reasoning, programming language theory, and cloud security to real-world systems at AWS and Bridgewater Associates. He blends deep academic grounding from Dartmouth (AB and PhD work) with hands-on engineering across backend, DevOps, and reverse engineering, evidenced by contributions to high-profile open-source projects like Swift Foundation, Scalaz, and Nix. His work often targets build reliability and correctness—fixing compilation issues, hardening sandboxing and download resilience, and refining functional data structures—showing a pragmatic focus on reproducible builds and robust tooling. Based in Richland, WA, he thrives at the intersection of security and low-level systems, bringing unusual breadth from protocol/binary reverse engineering to purely functional package management.
