Alex Delannoy contributed to the argoproj/argo-workflows and red-hat-data-services/argo-workflows repositories by building features and fixes that improved workflow management and UI stability. He implemented temporal filtering for workflows via API, enabling users to query by creation and completion times, using Go and TypeScript across backend and frontend. Alex enhanced UI usability by adjusting default graph filter states based on local storage and stabilized clickable URL rendering to prevent formatting regressions. He also improved graph traversal robustness by introducing cycle detection in DFS sorters. His work demonstrated depth in API development, algorithm implementation, and cross-stack integration for workflow platforms.

Summary for 2025-04: Implemented cycle-aware DFS graph sorter in argoproj/argo-workflows to prevent infinite recursion by introducing a visiting set, enhancing graph traversal robustness and runtime stability for DAG workflows.

February 2025 — Argoproj/argo-workflows: Delivered Temporal Filtering for Workflows via API (Created Since, Finished Before). Implemented backend changes and frontend integration for workflow listing and selection; fixed related API filtering issues (Fixes #13151, #13962). This work enhances discoverability, faster filtering, and automation readiness for workflows, and demonstrates solid API design and cross-team collaboration.

In November 2024, delivered targeted UI stability fixes for clickable URLs in Argo Workflows across two repositories, significantly reducing UI formatting regressions and improving user experience for workflow management. Implemented changes by wrapping rendered linkified text in a single span to preserve structure and avoid unintended formatting disruptions. The work aligns upstream and downstream efforts to provide a consistent, reliable UI.

In Oct 2024, delivered a targeted UI/UX improvement in red-hat-data-services/argo-workflows by implementing Graph Filters Default States From Local Storage. The new logic initializes the graph filter options 'showInvokingTemplateName' and 'showTemplateRefsGrouping' from localStorage, enabling them only when stored as true. This change reduces initial UI clutter, improves first-run experience, and aligns with usability goals while preserving existing behavior for users who have set preferences. The work is linked to issue #13835 and validated through code review and targeted UI checks.
