LangChain and LLM Agent Notebook Implementations
Authored dozens of open-source Jupyter notebooks with thousands of stars demonstrating tool integration, multi-agent debate, and local RAG retrieval pipelines.
Notebook workflows require refactoring into stateless services for production high-concurrency environments.
LoRA and QLoRA Fine-Tuning of Open Weights Language Models
