Summary
🤩
RockstarDan Pittman is a Technical Lead in cryptography with 13 years of engineering experience, currently optimizing libcrypto for Intel platforms through handwritten x86/AVX-512 assembly to accelerate RSA, XTS, and MD5. He blends low-level performance engineering with a background in safety‑critical software, formal methods, and verification—working across C, Rust, Agda and Haskell—so he reasons about both correctness and speed. An active open-source contributor, he has improved telemetry and code-review tooling (notably subscription management in intelsdi-x/snap and GPG signing in google/git-appraise), demonstrating practical attention to tooling and security. Based in Portland, OR, he pairs a mathematician’s curiosity with pragmatic engineering, often choosing the minimal, provably correct path to squeeze out measurable performance gains.

Contributions summary:Dan primarily contributed to the development of subscription management features within the "snap" repository. This involved implementing a "Subscriptions" type with basic increment, decrement, and read capabilities for an "AP" (likely referring to an "Available Plugin"). The user refactored code to align metrics with subscriptions instead of APs. These changes involved modifications to existing code, and related testing.

Contributions summary:Dan primarily contributed to the implementation of features related to signing and verifying code review requests and comments within the `git-appraise` system. They introduced GPG signing functionality, including the ability to sign and verify requests and comments using a user's configured key. Additionally, the user enhanced the `pull`, `submit`, `accept`, `reject`, `abandon`, and `rebase` subcommands to integrate signing and verification. Their changes required modifications to core structures such as `Comment` and `Request` to include signing capabilities.
