PROFILE

Serge S. Gulin

Over a three-month period, contributed to haskell/cabal and idris-lang/Idris2 by expanding cross-platform build support and improving compiler internals. Delivered Windows Aarch64 support in Cabal, enabling both cross-compilation and native builds through architecture detection and conditional compilation, and later aligned Windows API calling conventions to reduce build warnings and enhance CI reliability. In Idris2, implemented foundational refactoring for ScopedSnocList and scoped data structures, introducing new modules for safer name scoping and list manipulation. Work focused on maintainability, extensibility, and reducing technical debt, utilizing Haskell and Idris with expertise in build systems, C API integration, and type system design.

Delivered a targeted cross-architecture improvement for haskell/cabal in April 2025 by aligning the Windows AArch64 API calling convention with x86_64 support. This reduced build warnings, improved cross-arch compatibility, and stabilized Windows CI for AArch64 environments. The change is small, self-contained, and traceable to a single commit, enabling easier review and rollout.

Summary for 2025-01: Focused on expanding platform support and stabilizing the build workflow for cross-platform development. Delivered Windows Aarch64 support in Cabal build system, enabling both cross-compilation and native builds on Windows, with architecture detection, conditional compilation paths, and build path generation. No major bugs fixed this month. Overall impact includes broader platform coverage, improved build reliability, and reduced manual workaround time for Windows Aarch64 developers. Skills demonstrated include cross-compilation, Windows toolchain integration, architecture detection, and build-system customization.
