Apr 1, 2025April 2025 monthly summary for finnishtransportagency/geoviite focused on delivering topology-aware switch linking and enhanced visualization to improve track layout accuracy and debugging visibility. Work spanned two main features: Switch Linking and Topology Integration, and Visualization Improvements for Linking Points. The integration blends topology calculations with linking logic, expands test coverage for edge cases, and wires results to the DB for persistence. Visualization gains improve debugging and spatial analysis with enhanced point rendering and line drawing on the debug layer.

Mar 1, 2025March 2025 — Delivered two core improvements in Finnish Transport Agency's Geoviite (finnishtransportagency/geoviite). Key deliverables: 1) Dropdown UX bug fix to prevent blank searches from clearing selections and to preserve current search on outside-click/popup close; 2) Switch Linking & Fitting Enhancements introducing new data structures and utilities for the track layout system, refactored logic, support for mapping fitted switches to graph edges, and improved track geometries, with added tests to boost accuracy and reliability. Business impact: smoother user workflow, fewer manual corrections, and stronger data integrity in layout calculations. Technologies demonstrated: frontend UX, data-structure design, refactoring, testing, and Git-based version control.

Nov 1, 2024Month: 2024-11. Focused on delivering a major enhancement to the publication workflow in finnishtransportagency/geoviite by implementing an Enhanced Publication Preview and Staging Workflow with Map Visualization. The work centralized geometry-change tracking for location tracks, introduced map-based visualization and selection of publication candidates, and enabled staging of changes within publication groups. UI/UX refinements improved the preview table and map interactions, enabling faster reviews and fewer manual steps. A set of UX-driven PoCs and backups (Preview improvements POC and backup publication candidate map presentation) were conducted to validate resilience and UX readiness. These efforts contributed to a more reliable, auditable publication process and improved decision support for map data releases.
