PROFILE

Johannes Wachter

Worked on the symfony/ai-store repository to deliver four new features over two months, focusing on advanced search and documentation tooling. Developed a unified query abstraction layer supporting vector, text, and hybrid queries, and implemented a hybrid retrieval system with platform-level reranking to improve document search and retrieval. Enhanced documentation loading by introducing RstLoader and RstToctreeLoader for parsing reStructuredText and handling toctree directives, increasing compatibility and robustness. Added a PreQueryEvent hook for query customization and improved word-level parsing in search queries. All work was delivered in PHP using Symfony, emphasizing modular design, event-driven architecture, and thorough unit testing practices.
