Worked on the gamecon-cz/gamecon repository, delivering eight features and resolving key bugs over three months. Developed robust admin panel and backend functionality, including payment QR code generation, duplicate user detection with XLSX export, and a reporting system for granted discounts. Enhanced data integrity by refactoring the database schema, introducing dedicated tables, and removing obsolete constraints. Improved navigation reliability with a new page redirects feature and stabilized the test suite to support maintainable development. Utilized PHP, SQL, and HTML to implement these solutions, focusing on code refactoring, database management, and testing to ensure scalable, reliable operations and streamlined workflows.
January 2026 performance summary for gamecon-cz/gamecon: focused on data integrity, navigation reliability, and test stability to maximize business value and developer velocity. 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. Major bugs fixed: - Test Suite Maintenance: stabilized tests by blocking specific test URLs and removing outdated NewsletterSubscription tests to reflect current focus and clean up the test suite. 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 - Test pattern hygiene and suite maintenance (blocking URLs, removing outdated tests), improving CI reliability.
