PROFILE

Moritz Angermann

Over four months, this developer focused on build system reliability and cross-platform deployment for Haskell projects, contributing to IntersectMBO/cardano-base, IntersectMBO/cardano-cli, and IntersectMBO/ouroboros-network. They stabilized haskell.nix builds and restored Windows cross-compilation, improving CI reliability by refining dependency management and build configurations using Nix and Shell scripting. For cardano-cli, they enabled reproducible, statically linked macOS builds, reducing deployment complexity and runtime dependencies. In ouroboros-network, they delivered a fully static dmq-node executable for musl64 environments by overriding key dependencies and establishing a robust cross-compilation workflow. Their work emphasized maintainability, reproducibility, and streamlined deployment across diverse platforms.

Oct 1, 2025

Monthly summary for 2025-10 focused on IntersectMBO/ouroboros-network deliverables. Key features delivered include a static build for the dmq-node executable with a cross-compilation packaging strategy, enabled by introducing a new dmq-node-static package targeting a musl64 environment. This work required overriding several dependencies to ensure static libraries are used, specifically libsodium-vrf, secp256k1, gmp, and libblst. Commit 0d2ca293015fc77b576733e1ce16eee8dcda5cc3 to track the change.

May 2025 monthly summary focusing on stability and component-based build improvements in Cabal. Implemented robust multi-component Configure build handling to ensure configure runs only for main library and executable components, with other components falling back to Simple. This prevents concurrent execution issues and improves compatibility with component-based Cabal projects.
