Fine-tuned an open-source LLM to perform structured attribute extraction, intent classification, and taxonomy enrichment at inference time, replacing paid APIs and delivering significant cost savings while maintaining data quality for downstream embedding training.
Designed and deployed a large-scale offline data curation pipeline for foundation-model training: enriched product data via the fine tuned LLM before embedding creation, improving semantic consistency and retrieval performance.
Fine-tuned large-scale multimodal embedding models serving mainly two downstream consumers: (1) an agentic ads-in-chat product (ChatGPT-style) requiring high-precision semantic retrieval, and (2) a recommendation system using FAISS, k-NN, and Elasticsearch for large-scale product ranking.
Served as technical interface with external partners (e.g., Anyscale), contributing to architectural decisions, production-readiness reviews, and distributed training best practices.
Ran privacy audits on Criteo models to ensure no data was leaked during training,
