PROFILE

Athma Sagar

Worked on stabilizing and improving build reliability for the facebook/fbthrift and facebook/buck2-prelude repositories, focusing on bug fixes that enhanced determinism and reduced runtime errors. Addressed hashing inconsistencies in C++ by reverting to a manual approach and resolved Bazel native.bzl loading issues through precise dependency management. In Buck2 Prelude, fixed flaky dwp actions by dynamically including hidden dependencies in the build process and improved Python wheel deployments by ensuring native libraries loaded via torch.ops.load_library were correctly linked. Leveraged skills in C++, Python, and build system configuration to deliver more robust, maintainable, and predictable development workflows across both projects.

October 2025: Key fix to Python wheel loading by dynamically including native dependencies in the link graph. Expanded the omnibus search space to account for native libraries loaded by Python, updated the python_wheel.bzl _impl to include these dependencies via SharedLibraryInfo, and ensured proper recognition of libraries loaded through torch.ops.load_library. This work reduces runtime errors and improves reliability of wheel-based deployments in Buck2-prelude, contributing to more stable PyTorch-related workflows and faster onboarding for downstream users.

August 2025 (facebook/buck2-prelude): Consolidated a critical bug fix to eliminate flaky dwp actions by ensuring all hidden dependencies are included in the final link. The change updates cxx_gnu_dist_link to dynamically reference these dependencies, addressing regressions caused by cache hits on late-stamped, local-only actions. Result: more stable builds, fewer flaky failures, and improved determinism in the Buck2 Prelude pipeline.
