Yannik Hayn
Worked on the CactuseSecurity/firewall-orchestrator repository, delivering features and fixes across backend, API, and UI layers to enhance security orchestration workflows. Focused on robust reporting, data integrity, and user experience, this developer implemented cursor-based pagination, advanced filtering, and timezone normalization using C#, Blazor, and GraphQL. They improved API reliability by supporting large IDs, standardized data filtering, and optimized SQL queries for accuracy. UI enhancements included consistent navigation, responsive layouts, and asynchronous testing for reliability. Automation and DevOps improvements leveraged Ansible and Python scripting to streamline deployments and enforce script safety, while comprehensive test coverage ensured maintainable, scalable code quality.

Mar 1, 2025March 2025 (CactuseSecurity/firewall-orchestrator): Implemented performance- and data-integrity-focused enhancements across the Right Sidebar, Rule Details/RSB reporting, API, and UI layers. Key deliveries include a Right Sidebar Data Loading and Pagination Overhaul with cursor-based pagination and refined lazy fetching; Rule Details and RSB Reporting Enhancements with negation handling, inactive-rule support, and optimized data loading; Time and Reporting UI Stability improvements with synchronized time filters and safer UI interactions. Critical fixes addressed data quality and API completeness: Unique Management Data Lists (deduplicated objects/services/users) and Network Ownership API Completeness (nw_type present and safe is_deleted defaults). These changes improved data accuracy, reliability, and performance, delivering measurable business value in faster insights, cleaner UI, and safer data handling.

Dec 1, 2024Month: 2024-12. This period focused on hardening the Right Sidebar (RSB) UX, robust cross-report navigation, and consistent UI across the firewall-orchestrator. Key outcomes include: 1) Location-aware RSB collapse/expand with auto-scroll and dependency-aware render order to keep related components visible and reduce user confusion; 2) Robust RSB linking across reports, certification, and tests via URL fragments, with proper ID handling and added unit tests and mock data for validation; 3) UI styling and layout polish that aligns the navbar with the sidebar and standardizes TabSet styling for a cohesive experience. In parallel, targeted fixes improved reliability (collapse behavior with RSBLocation prefixes, correct links in cert pages, and navbar height consistency). Overall, these changes deliver faster access to critical sections, reduce navigation errors, and improve maintainability. Technologies/skills demonstrated include front-end architecture, responsive UI, URL-based navigation, automated tests (unit and mock data), and CSS/class management for consistent styling.
