Nov 1, 2025In November 2025, delivered the Contest Visibility Toggle feature for OpenJudgeSystem. Administrators can show/hide hidden exams via a new UI button; backend filtering now supports visibility-based contest filtering. This work is linked to issue #1734 and committed in ce4f247911de6e90956a5b02b6fd87a4070ad65e. No other major bugs fixed in this scope. Impact: enhances content moderation efficiency, reduces risk of exposing hidden exams to unauthorized users, and establishes a scalable foundation for visibility policies. Technologies/skills demonstrated: frontend admin controls, backend filtering logic, admin-only access patterns, and robust change-tracking with issue linkage.

Aug 1, 2025August 2025 focused on reliability, performance, and developer productivity for SoftUni-Internal/OpenJudgeSystem. The team delivered four key feature areas, stabilized critical flows, and improved data paths that drive contest analytics and test execution. Key outcomes: - Refined csproj cleanup: Extended RemoveReferencesFromCsProj to remove global usings, followed by a targeted refactor that simplified package removal logic and adjusted execution strategies. - JavaScript sanitization overhaul for SPA tests: Introduced a dedicated JavaScriptSanitizer and centralized SanitizeContent across execution strategies; applied SPA-specific sanitizers for test execution. - Contest viability and submission controls: Enhanced contest visibility with past-starting contests and introduced configurable settings for how long post-end submission limits are adjusted. - Contest results data retrieval optimization: Refactored data retrieval to fetch only official participants’ scores and relevant problem details, eliminating redundant queries and improving data efficiency. Major bugs fixed and reliability improvements: - Stabilized global-usings handling in csproj cleanup to prevent inconsistent builds. - Reduced test flakiness by centralizing sanitization logic and eliminating divergent paths in SPA tests. - Improved data-query performance by removing an expensive GetAllByContestWithScoresAndProblems path in favor of targeted data retrieval. Overall impact and accomplishments: - Faster, more reliable build and test pipelines, more predictable contest analytics, and a better experience for contest administrators and participants. The changes reduce maintenance overhead and set a scalable foundation for upcoming features. Technologies/skills demonstrated: - C#, CSProj manipulation, and refactoring of execution strategies - Frontend/test tooling: JavaScript sanitization, SPA testing approaches - Data services and query optimization, including selective data loading - Feature configuration and visibility controls for contest features
