PROFILE
Edsko De Vries
Edsko de Vries developed and maintained the well-typed/hs-bindgen repository, delivering a robust C and C++ to Haskell binding generator. Over ten months, Edsko refactored core parsing and code generation pipelines, introduced modular AST manipulation, and improved error handling and diagnostics. By leveraging Haskell, C, and C++, Edsko enhanced cross-language type safety, streamlined macro and enum processing, and expanded support for complex C constructs. The work included build system integration, test infrastructure improvements, and comprehensive documentation, resulting in a maintainable, extensible codebase. Edsko’s engineering demonstrated depth through careful abstraction, rigorous testing, and thoughtful API and internal tooling design.

Jun 1, 2025June 2025 - well-typed/hs-bindgen: Delivered a frontend replacement and core API refactor, expanded Clang bindings, and overhauled parsing/AST internals for better reliability and maintainability. Implemented an AST folding/resolution overhaul, introduced HsBindgen.Clang, and enhanced the parser with separate monads for types/decls, plus improved error handling and variadic function support. Strengthened build tooling and project structure, added ConstantArray utilities, and performed essential cleanup (Licensing, unused files, submodules).
