Kandl
Matyas Kandl developed and enhanced core features for the gooddata-ui-sdk repository, focusing on scalable dashboard analytics, robust automation, and export capabilities. He engineered a Pivot Table component using React and TypeScript, leveraging ag-Grid’s server-side row model to support large-scale data exploration with sorting and totals. His work included optimizing dashboard filter loading, implementing execution cancellation with AbortController, and expanding export options to XLSX, PDF, and PPTX formats. By refining state management with Redux and improving UI/UX consistency, Matyas addressed reliability, performance, and usability challenges, delivering solutions that improved data visibility, automation workflows, and reporting for end users.

Jul 1, 2025In July 2025, delivered a Pivot Table Component built on ag-Grid with server-side row model, enabling scalable pivot analytics with sorting and totals, complemented by Storybook examples for multiple use cases. Also fixed UiTreeview validation issues by correcting a SCSS trailing comma and refining TypeScript definitions, improving build reliability and type safety. These efforts enhance data exploration capabilities for large datasets, reduce UI defects, and accelerate adoption through comprehensive documentation and examples.

Jun 1, 2025June 2025 performance summary for gooddata-ui-sdk: Focused on delivering tangible business value through dashboard UX improvements, export capabilities, and robust automation, while improving data visibility and layout consistency. Key deliverables: - Dashboard UX and Export Enhancements: Speeded up filter loading, preserved compatibility with older saved configurations, and added export capabilities for dashboards to PDF/PPTX with overrides; refined display form options for attribute filters. Notable commits include fixing dashboard attribute filters, marking older schedules/alerts as invalid, and enabling export to presentation commands. - Alerts and Automation Robustness: Hardened automation/alerts to gracefully handle missing notification channels and ensured ad-hoc filter changes do not disable essential alert actions. - Pivot/Table and Layout UI Improvements: Improved data visibility and layout consistency by showing full pivot table values via tooltips and ensuring layout transforms apply when the focused object is empty. Impact: - Enhanced user experience and faster dashboard interactions; expanded export options support sharing and reporting needs; greater resilience of alerting workflows; improved data readability in complex dashboards. Technologies/skills demonstrated: - Front-end performance optimization, UI/UX design, backward compatibility, robust error handling, and layout transformation management across dashboards, alerts, and data presentation components. Business value: - Shorter time-to-insight for stakeholders, streamlined reporting via exports, and reduced operational risk through reliable alerts and consistent UI.
