AI Architect/Developer – Retrieval-Augmented Generation (RAG) and LLM Evaluation

Text
Directed the design, development, and operation of a retrieval-augmented, LLM-integrated AI learning platform. Implemented evaluation mechanisms for LLM recall, precision, and system stability tailored to production AI models. Championed the iterative improvement of LLM retrieval logic and continuous assessment of AI-generated text quality. • Built evaluation workflows for recall and precision measurement. • Led continuous improvement and QA cycles with feedback loops. • Developed containerized environments for robust data flows in training. • Prioritized performance benchmarks and ongoing model retraining.

AI/Software Architect/Developer – AI Model Evaluation and LLM Tuning

Text
Designed and implemented mechanisms for evaluation and continuous improvement in AI-powered applications, particularly focusing on retrieval quality and LLM performance. These systems measured factors such as Recall@k and Precision to assess model outputs, helping drive higher accuracy and reliability. Played a key role in prompt engineering and system tuning for LLMs and Retrieval-Augmented Generation solutions. • Developed and optimized evaluation pipelines for LLM-generated text. • Applied prompt engineering techniques to train and improve AI responses. • Measured outputs for performance benchmarks and retrieval accuracy. • Collaborated on RAG and LLM systems to iteratively refine AI-driven workflows.
