PROFILE
Zhen-kai Gao
Worked on CARTAvis/carta-frontend over eight months, delivering features and fixes that improved data accessibility, UI reliability, and workflow efficiency. Developed enhancements such as a modular hotkey management system, spherical-geometry-based spatial calculations, and colormap visualization with Python scripting for preview generation. Addressed frontend issues by stabilizing API integrations, refining WCS-based image rendering, and preventing memory leaks in MobX reactions. Leveraged TypeScript, React, and Node to implement robust state management and automated code quality checks in CI/CD. The work emphasized maintainability and correctness, resulting in a more stable, accurate, and user-friendly platform for astronomical data exploration and visualization.

Dec 1, 2025December 2025: CARTAvis/carta-frontend delivered two major frontend enhancements that drive business value by expanding data accessibility and improving image viewing consistency. The Catalog API now retrieves all VizieR columns, enabling richer data exploration for users. The Image Viewer UI polish fixed multi-panel alignment in partially filled layouts and added text wrapping in the cursor info bar to prevent overflow in narrow panels. These changes reduce the need for manual field requests, improve readability, and accelerate data inspection workflows across teams.

Sep 1, 2025September 2025: Delivered a critical stability improvement for the PV workflow in CARTAvis/carta-frontend by fixing the PV Generator Widget visibility. The patch ensures the widget remains visible and functional when a new PV image is generated while another PV image is open, preventing premature closure and reducing user disruption across PV generation sessions.
