About Sarah Ewing

At Unify Consulting, leveraging prompt engineering and retrieval augmented generation (RAG) workflows has revolutionized large language model performance. This approach has not only streamlined the development process but also established a robust framework for continuous LLM experimentation and optimization. Our team's innovative strategies in few-shot learning have significantly enhanced efficiency across Llama 2 & 3, Minstrel, and StratChat2 models.Previously, as a small business owner, my focus was on implementing cutting-edge data strategies and creating tools for feature engineering and data dimension reduction. This culminated in the productionalization of generative AI for operational business use cases, employing python azure functions for seamless integration. These efforts have facilitated a direct impact on sales and customer engagement, demonstrating a commitment to practical, results-oriented data science solutions.
