Summary
🤩
Rockstar🎓
Top SchoolDaniel Paoliello is a Senior Software Engineer with 11 years of experience at Microsoft focused on bringing Rust to Windows and Azure, blending deep systems-level work with cloud connectivity for SQL client libraries and networking. He has contributed to high-profile open-source projects like rust-lang/rust and cargo—adding Arm64EC Windows target support and improving Cargo's path dependency handling—plus targeted LLVM changes to support Windows AArch64 toolchains. Daniel combines compiler and toolchain expertise with pragmatic product development for enterprise platforms, making him fluent in low-level code generation, target specs, and real-world interoperability challenges. Prior roles in IT consulting and web support, together with a BSc (Hons) in Computer Science from Curtin University, give him a strong foundation in architecture and cross-team delivery. A less obvious strength is his ability to navigate both upstream open-source collaboration and internal cloud product requirements, translating research-grade changes into production-ready Windows and Azure integrations.

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Role in this project:
Back-end Developer
Back-end DeveloperContributions:98 reviews, 75 PRs, 38 pushes in 4 years 6 months
Contributions summary:Daniel primarily contributed to the LLVM project by implementing features related to the Arm64EC architecture. Their work included modifying the name mangling algorithm for Arm64EC symbols, adding support for MSVC intrinsics like `__addx18...` and interlocked pointer intrinsics, and fixing thunks for vector arguments within the Arm64EC context. Additionally, the user made fixes related to build breaks in MSVC, and implemented import call optimization for AArch64 Windows, which involved adding a new section to the obj file. They also addressed a range of issues related to Windows x64 unwind data.

The Rust package manager
Role in this project:Back-end Developer
Back-end DeveloperContributions:39 reviews, 7 PRs, 52 comments in 2 years 6 months
Contributions summary:Daniel contributed to the Cargo package manager by implementing features related to path dependencies and path base configurations, a core aspect of the Rust package management system. Their work included adding support for the `--base` option in `cargo add`, modifying dependency handling logic, and updating TOML parsing to accommodate path base configurations. They also fixed issues and normalized newlines in the documentation rendering process for Cargo.
