PROFILE
Felipe De A. Mello Pereira
Worked on the google/crubit repository to enhance Rust and C++ interoperability, focusing on build system reliability, documentation accuracy, and test stability. Delivered features such as raw pointer accessors for Rust bindings, dependency propagation in Bazel rules, and C-compatible memory layouts for string types. Addressed build reproducibility by updating LLVM dependencies and refining build target compatibility, while also fixing golden tests and clarifying documentation to reduce onboarding friction. Utilized Bazel, C++, and Rust to streamline cross-language integration, improve debugging, and harden the build graph, resulting in more stable releases and smoother downstream adoption for Rust/C++ component integration.

Aug 1, 2025August 2025: Strengthened Crubit bindings for Rust-C++ interop, stabilized the binding surface, and hardened the BUILD graph to improve reliability and velocity. Key deliverables and impact: - Interop bindings: Marked cc_std::std::string as repr(C) for a C-compatible memory layout and added Debug implementations for string_view and raw_string_view to aid debugging in composite structures (commits cc5f31c712bce7f588cddf11245b1aef4d33751f, 498d1be220692fdb94038dee1f2df49cd7d859b0). - Test stabilization: Fixed golden tests and aligned test annotations across multiple files to stabilize Crubit bindings tests (commits cc27976cba034e31d138cd0a06d4082378499161, 5b19ff28aee0ee240fcc65222c9b2b7bbd7e9bac). - Build graph hardening: Refactored bindings aspect logic to ensure Crubit aspect is applied to all targets in cc_deps and reorganized provider definitions and utilities to prevent circular dependencies in the BUILD graph (commit fa18d4f9b6eae3e28634e693eb29d997b5b52561). Overall impact: improved interop reliability, easier debugging, fewer test flakes, and a more stable build graph, enabling faster downstream adoption and safer integration with Rust/C++ components. Technologies/skills demonstrated: Rust, C/C++ interop, Bazel/BUILD graph, Crubit bindings, test engineering, debugging proficiency.
