PROFILE
Simon Marlow
Over a two-month period, this developer focused on modernizing Haskell code indexing across core repositories such as facebook/fboss, CacheLib, fbthrift, and sapling. They redesigned the Haskell indexer to read .hie files directly, simplifying the indexing pipeline and improving both cross-reference coverage and performance. Their work included schema redesigns to capture richer information and enhance correctness, leveraging skills in Haskell, static analysis, and software architecture. Additionally, they addressed a critical build issue in facebook/fbthrift by removing a circular dependency in the CMake build system, stabilizing shared library builds and reducing maintenance risk for downstream projects.

Mar 1, 2026March 2026 monthly wrap-up for facebook/fbthrift: Delivered a critical fix to enable BUILD_SHARED_LIBS by removing a circular dependency between thrifttype and thriftanyrep, improving build stability for shared library configurations. The change prevents build failures when building with shared libraries and reduces downstream maintenance risk. The work was validated via cross-repo verification (hsthrift PR 174) and landed as fbthrift PR 692 (Differential Revision: D96944523).
