Worked on backend development and documentation across two open source projects, focusing on practical improvements and reliability. In the YOURLS/YOURLS repository, addressed a MySQL 8+ installation issue by refining SQL string handling in PHP, ensuring proper escaping and compatibility for database table creation. This fix reduced installation errors and improved cross-version support. Later, contributed to mudler/LocalAI by updating documentation metadata to better position the product as a local AI stack for language models and agents, enhancing clarity in external sharing platforms like Slack. Demonstrated skills in SQL, PHP, and technical documentation, with a focus on targeted, maintainable enhancements.
