PROFILE
Anders Rantala Hunderi
Contributed to equinor/webviz-subsurface-components by developing and refining advanced data visualization features for subsurface analysis. Focused on React and TypeScript, the work included refactoring core components like GroupTreePlot and Well Log Viewer for improved maintainability, type safety, and user experience. Integrated D3.js for complex data calculations and enhanced UI elements such as collapsible nodes and resizable plots. Addressed critical bugs affecting log rendering and visualization accuracy, while reorganizing utility code to streamline maintenance. Enhanced the Subsurface Viewer’s picking system using Deck.gl and GeoJSON, improving multi-selection accuracy and reliability for end users working with complex well data.

Jan 1, 2026January 2026 monthly summary for equinor/webviz-subsurface-components: Delivered a major refactor of the Wells log visualization by introducing a dedicated sub-layer (LogCurveLayer) and UI improvements, resulting in cleaner separation of log curves, improved alignment with trajectory paths, and clearer property names. Fixed critical issues in the log layer and related UI, enhancing selection behavior and 3D rendering quality. Established groundwork for the wells-layer data model change (#2661) and achieved a substantial reduction in wellsLayer size to improve maintainability and performance.

Oct 1, 2025Month 2025-10: In equinor/webviz-subsurface-components, delivered a major enhancement to the Subsurface Viewer by revising the picking system to support multi-pick radius with bounds enforcement, improving accuracy and user experience. As part of this work, the coords prop was deprecated in favor of explicit, intuitive picking configuration. These changes, tied to the commit f427e0fe7d9d9c6dec5356d29855f3414370fd07 (fix: [Subsurface Viewer] Fix picking radius for multi-picking and clamp interpolation (#2621)), reduce interpolation errors and prevent depth values from exceeding wellbore limits.

Apr 1, 2025April 2025: Focused on delivering robust subsurface visualization features and stabilizing rendering paths in the absence of track data. Key outcomes include enhanced Wells Layer multi-pick UX, better handling of overlapping wells, and improved Well Log Viewer reliability when tracks are missing. These changes improve data handling, user workflow reliability, and overall visualization fidelity.

Mar 1, 2025March 2025 performance summary for equinor/webviz-subsurface-components: Key features delivered include the WellLogViewer Architecture Refactor and Usability Enhancements, which reorganized utilities (splitting large utility files, reassigning responsibilities to WellLogViewer.tsx) and rewrote track management to improve usability. Major bug fixed: area and gradient plots now render with visibility by default after correcting default fill-opacity from 0 to 0.25 when no fill color is specified. These efforts improve maintainability, reduce bug surface, and enhance end-user experience. Technologies/skills demonstrated include React/TypeScript refactoring, modularization, and disciplined commit hygiene. Commit references are included for traceability.
