AI / LLM Engineer

Ineffable Interiors • Temps plein

Feb 2025 - Oct 2025 • 8 mos

 Designed LLM-powered applications combining retrieval, embeddings, structured generation, and backend services.  Architected RAG workflows for enterprise knowledge discovery, including ingestion, chunking, retrieval, reranking, context construction, and grounded generation.  Reduced fine-tuning GPU memory consumption by approximately 60% using QLoRA, allowing larger models to be trainedonthe available GPU infrastructure.  Developed evaluation workflows for answer quality, retrieval relevance, latency, reliability, and model cost.
