I would build ingestion and chunking pipelines, generate embeddings, store them in a vector database, implement retrieval and reranking, and connect the context to an LLM with grounded prompting. I would then evaluate answer quality, citation accuracy, latency, cost, and hallucination rates before deploying monitoring and feedback loops. What practices do you use to monitor ML models after deployment? I track operational metrics such as latency, error rate, throughput, and cost alongside model metrics such as accuracy, relevance, drift, bias, and reliability. I establish baselines and alert thresholds, log inputs and outputs with appropriate privacy controls, and investigate degradation through reproducible evaluation datasets. When needed, I implement rollback, retraining, prompt updates, or data-pipeline remediation. Describe how you would deploy an LLM-powered service as a scalable API. I would package the service in containers, expose clear REST or asynchronous endpoints, and separate orchestration, retrieval, model-provider access, and business logic into maintainable components. I would use authentication, rate limits, structured logging, caching, retries, and observability to support reliability. Horizontal scaling, queue-based background processing, and cost controls would be selected based on expected traffic and latency requirements. How do you decide whether to fine-tune an LLM or use prompting and RAG? I first evaluate whether the gap is factual knowledge, task behavior, format consistency, or domain language. RAG is usually preferable for changing or proprietary knowledge because it can provide current, traceable context, while prompting can solve many behavior and workflow needs quickly. I consider fine-tuning when a stable task requires consistent behavior or specialized output patterns that cannot be achieved reliably through prompting and retrieval alone. How do you translate an ambiguous client problem into an AI solution? I begin with stakeholder interviews to define the user, decision process, current workflow, data availability, risks, and measurable business outcomes. I convert these findings into a scoped use case, success metrics, architecture options, and a phased proof of concept. I communicate assumptions and trade-offs clearly, validate results with users, and prioritize an implementation that is practical, measurable, and maintainable. Next step ## Apply now.
