Apr 1, 2026April 2026: Delivered RadialFeedback Overlay for Image Viewer in zooniverse/front-end-monorepo. Implemented RadialFeedback component that renders an SVG overlay of annotation feedback on the single image viewer, supporting coordinates (x, y) and (x_center, y_center) and respecting hideSubjectViewer rules. Refactored drawing tools to consume the full MST mark object, removed FEEDBACK_MARK, and updated tests. Visual polish with semi-transparent fills and lighter marks. Documentation updated. No critical bugs fixed this month; focus on feature delivery, code quality, and maintainability. Business impact: improved annotation UX, clearer feedback, and higher data quality; faster classification assessment. Technologies: React, SVG overlays, coordinate-based marking, MST model usage, test refactoring, code style.

Mar 1, 2026March 2026: Key feature delivered is Dynamic Textarea Auto-Resizing for the zooniverse/front-end-monorepo, enabling textarea inputs to expand and shrink based on content, removing unnecessary scrollbars and improving layout handling for text tasks. Height calculation moved from a resize-based approach to a layout-effect computation, resulting in more stable rendering and fewer layout churn. This work enhances the UX for content entry and contributes to more maintainable, reusable components across the front-end. No major bugs fixed this month; stabilization work focused on refining the text task inputs.

May 1, 2025Month: 2025-05 | Product area: zooniverse/front-end-monorepo. This month focused on robustness and workflow efficiency in the SVG image viewer and classifier flow. Key features delivered: improved classifier UX by enabling immediate subject advancement after Done (without requiring Talk) and refactoring the image scaling logic to be robust when the canvas is not yet available. Major bugs fixed: defense-in-depth fixes for SVG subject image scaling ensured canvas elements exist before performing scale calculations; refactored useScale hook and related helpers to safely handle cases where the canvas is not yet available, preventing errors in the image viewing component. Overall impact: reduced workflow friction for classifiers, fewer runtime errors in image rendering, and a more reliable subject viewing experience; contributed to faster throughput and clearer code surfaces. Technologies/skills demonstrated: React hooks refactor (useScale), defensive programming for canvas readiness, clean commit traceability, and feature-driven workflow improvements.
