Contributed to the HGustavs/LenaSYS repository by building and refining advanced diagram modeling and UI systems over two months. Focused on enhancing lifeline and multi-line diagram features, introducing recursive line support, and implementing autosave to improve data reliability. Developed a cohesive UI foundation with a functional Floating Action Button, customizable popups, and a comprehensive button and navigation system. Applied CSS, JavaScript, and HTML to migrate styling to external stylesheets, improve code readability, and streamline event handling. Addressed bugs related to line rendering, UI interactions, and cardinality, while maintaining code quality through documentation, refactoring, and workflow alignment for collaborative development.
May 2025 – LenaSYS development focused on delivering a cohesive UI foundation, richer FAB interactions, robust button/navigation systems, and targeted quality improvements to stabilize the UX and speed feature delivery. Key features delivered include a functional Floating Action Button (FAB) with a customizable popup, promise-based handling, and support for sub-buttons; UI foundation enhancements with initial HTML/CSS structure and migration from inline styling to external stylesheets; a comprehensive Button System and UI Navigation (base, placements, events, and authentication-related buttons); line rendering enhancements and transitions (line-to-box, menu interactions, and updated drawing logic); and UX improvements such as backtracking capability and a refined zoom factor.

April 2025 focused on strengthening LenaSYS diagram modeling, reliability, and collaboration workflows. Key deliveries include lifeline/multi-line diagram enhancements with new line support and property validation; recursive line support with improved positioning and cardinality handling; UI stability improvements via Z-index adjustments and removal of a zoom artefact; creation offset adjustments and partial/placeholder work pacing for ongoing development; introduction of autosave to safeguard user data; and targeted code readability improvements and PR workflow alignments. Major fixes addressed error handling and ghostline checks, corrected cardinality creation parameters, and reverted a problematic change to preserve stability. The work significantly boosts diagram fidelity, reduces runtime issues, and accelerates cross-team collaboration.
