PROFILE
Alan Bjorklund
Worked on Ultimaker/Cura, delivering eight new features and two bug fixes over four months focused on 3D printer configuration, material profile management, and slicer logic. Enhanced material support and printer compatibility by adding new profiles for Sketch, Replicator+, and Method platforms, optimizing print speed and reliability. Addressed configuration issues and improved user experience through UI/UX changes, such as hiding gantry acceleration parameters to prevent misconfiguration. Utilized Python, JSON, and INI for configuration and software development, applying data-driven parameter tuning and cross-component integration. The work improved print success rates, reduced cycle times, and supported broader hardware and material compatibility within Cura.

Apr 1, 2025April 2025: Delivered a focused UI/UX enhancement in Ultimaker Cura to hide gantry acceleration parameters and related values from the speed adjustment workflow, preventing misconfiguration when increasing print speed. This change reduces user confusion, protects critical configuration mappings, and supports the 5.10.1 release scope. Commit be052ae74d634fa0deb043659b08856a80be1cd0 was the implementation. Impact includes safer defaults, clearer UI, and decreased risk of incorrect speed settings. Technologies/skills demonstrated: UI/UX design, front-end development, code review, release engineering, and cross-team collaboration.
