Embeddings & RAG Support
Real-time help building RAG on Hugging Face — chunking, Sentence Transformers embeddings, vector search, cross-encoder reranking, and evaluation to keep answers grounded and accurate.
A RAG system that retrieves the wrong chunks, hallucinates, or degrades after a model change? Most RAG quality problems are retrieval problems — chunking, embeddings, and reranking — not the LLM. We help you fix the retrieval layer.
We help you build and fix RAG end to end on the Hugging Face stack: document parsing and chunking strategy, embedding with Sentence Transformers (and serving embeddings via TEI), indexing in a vector database (FAISS, pgvector, Qdrant, Pinecone, Weaviate, OpenSearch, or Elasticsearch — these are third-party stores, not HF products), hybrid (dense + lexical) retrieval, cross-encoder reranking for precision, prompt construction and grounding, and evaluation of retrieval and answer quality. We also diagnose the specific failure of embedding-dimension mismatch after swapping embedding models, which silently breaks retrieval.
What We Offer
From daily job support to emergency production fixes, proxy interview guidance, and interview coaching — we have the expert for your specific need.
Hands-on help on real tickets — architecture, implementation, debugging, and code review on your actual Hugging Face stack (Transformers, PEFT, TRL, Diffusers, Sentence Transformers, huggingface_hub) during your working hours, not generic tutorials.
Firefighting for live incidents — GPU memory, latency, throughput, quantization, adapter loading, endpoint reliability, retrieval quality, and cost problems resolved with an LLM engineer on the call.
Hugging Face, LLM, and GenAI interview questions covered end-to-end plus profile positioning so you can both keep your job and land the next one.
