- Hands-on experience with LLM toolchains such as LangChain, LlamaIndex, or OpenAI APIs
- Recognized as a technical leader beyond your immediate team, influencing platform strategy across organizations
- Awareness of industry best practices and risks in GenAI including hallucination mitigation, fairness, explainability, and data privacy
