Johann Lee developed and enhanced retrieval-augmented generation (RAG) infrastructure for the kilian-group/phantom-wiki repository, focusing on multi-GPU support, reproducibility, and maintainability. He consolidated RAG core logic with mixin-based integration, implemented batched offline inference, and modernized launch scripts using Bash and Python. His work included refactoring agent initialization, optimizing evaluation workflows, and updating documentation to clarify model-specific behaviors. By addressing initialization coupling and improving argument parsing, Johann increased robustness and alignment with production LLM workflows. He also fixed stability issues and improved repository hygiene, demonstrating depth in backend development, distributed systems, and large language model integration over a concentrated two-month period.
