Adrijan Ed built and enhanced core features for the gamecon-cz/gamecon repository, focusing on data integrity, admin workflows, and maintainability. Over three months, Adrijan delivered an activity correction system with permission controls, duplicate user detection with XLSX export, and a QR code payment feature in the admin panel. He refactored legacy PHP scripts, improved database schema design, and introduced a dedicated event location table to streamline data relationships. Using PHP and SQL, Adrijan also implemented robust redirect logic and stabilized the test suite, resulting in more reliable navigation, cleaner code, and improved reporting capabilities for both users and administrators.

Delivered two core features and stabilized the test suite, driving data reliability, user experience, and maintainability. Key features delivered: - Database Schema Improvements and Data Integrity: update active year handling, guard sorting of data when present, removal of obsolete constraints/indexes, and introduction of a dedicated event location table with cleaner foreign keys to streamline data integrity. - Page Redirects Feature: added a redirect column, implemented redirect checks in the Stranka class, and updated the index.php flow to route users to alternate URLs when applicable.

Impact and accomplishments: - Improved data integrity and data quality, reducing downstream issues in reporting and features relying on event location data. - Smoother user experience and SEO-aware navigation via reliable redirects. - More maintainable test suite, reducing flaky tests and speeding up future changes. Technologies and skills demonstrated: - SQL/database schema design and refactoring (active year updates, data integrity constraints, new location table). - PHP logic and flow control (redirect checks in Stranka class, index.php routing). - Test pattern hygiene and suite maintenance (blocking URLs, removing outdated tests), improving CI reliability.
