PROFILE

Jeroen Hofstee

Worked on frontend and system-level improvements across victronenergy/gui-v2 and nodejs/node, focusing on reliability, maintainability, and user-facing features. Delivered a WebAssembly-based UI foundation and enhanced build packaging in gui-v2, using CMake and JavaScript to streamline deployment and asset management. Addressed translation build dependencies and standardized test formatting to stabilize CI workflows. In nodejs/node, contributed C++ memory management fixes, including ARM 32-bit alignment and zlib refactoring, reducing crash risk and technical debt. Added user controls for network interfaces in gui-v2, improving enterprise deployment flexibility. Demonstrated strengths in build system configuration, patch management, and cross-repo collaboration for robust software delivery.

Feb 1, 2026

February 2026 monthly summary for victronenergy/gui-v2. Delivered user-facing control for the link-local network interface in Network Settings, reducing network issues on MAC-secured switches by enabling users to disable the link-local interface via a new ListSwitch in NetworkSettingsPageModel. Implemented in a single commit (c0e8abc34d52f281cfa3e06c728364381b79f3ca), addressing Venus issue #1511 and aligning with existing network reliability goals. This change improves configuration flexibility for enterprise deployments and reduces potential downtime and support overhead related to network compatibility.

January 2026: No new user-facing features in nodejs/node; primary contribution was a critical bug fix improving ARM 32-bit memory alignment in the allocator. Implemented by NgLibMemoryManager::ReallocImpl to allocate the maximum of size_t and the required alignment, preventing unaligned accesses on ARM NEON and reducing crash risk. Reproducer documented; change reviewed by Matteo Collina, Anna Henningsen, and Rafael Gonzaga; PR-URL linked. Business value: enhanced stability for ARM deployments, reduced maintenance from crashes, and more predictable performance across architectures. Technologies: C++, low-level memory management, cross-arch alignment, NEON considerations, code-review discipline, PR workflow.

September 2025 highlights: delivered value through reliability improvements in frontend tests and a core library refactor in Node.js. In victronenergy/gui-v2, completed test suite whitespace normalization to standardize formatting, improving test reliability and maintenance without changing features. In nodejs/node, unified zlib memory offset calculation with a single constant, reducing code duplication and enhancing maintainability and clarity. These efforts reduce CI flakiness, lower technical debt, and enable faster, safer feature delivery across both repos.

Monthly summary for 2025-07 focusing on victronenergy/gui-v2. Delivered a critical build reliability improvement by fixing translation file generation order. Ensured lupdate runs after src/themeobjects.h is generated, preventing translation generation failures due to missing headers. Implemented via CMakeLists.txt: make lupdate depend on src/themeobjects.h. This stabilizes CI, reduces flaky translation-related errors, and improves release readiness for the GUI module.
