Domain-Specific AI Engineering

The future of production AI isn't one enormous model doing everything. It's the right models, data, retrieval, evaluation, and infrastructure working together for the right tasks.

Building a demo with a general-purpose LLM is easier than ever. Building a domain specific AI system that delivers accuracy, predictable latency, controlled cost, privacy, deployment flexibility, and long-term reliability is a very different challenge.

If you're an AI engineer, machine learning practitioner, software engineer, architect, or developer moving beyond basic LLM experimentation, you need more than prompts and isolated training recipes. You need a production AI engineering methodology for deciding when small language models are sufficient, when larger models are necessary, what belongs in retrieval, what belongs in model weights, and how to prove that your system is ready for production.

Domain-Specific AI Engineering gives you that complete framework:

Define → Select → Curate → Adapt → Evaluate → Optimize → Deploy → Observe → Improve

Rather than treating LLM fine tuning, RAG, evaluation, optimization, and deployment as disconnected techniques, Nolan Veyne shows you how to combine them into an evidence-driven engineering lifecycle.

Inside, you'll learn how to:

• Select and baseline small language models based on domain capability, latency, memory, hardware, privacy, and cost

• Build governed, traceable domain datasets for training, validation, benchmarking, and evaluation

• Apply domain adaptive pretraining, SFT, LoRA QLoRA, and preference optimization where they genuinely add value

• Make informed RAG fine tuning decisions and combine retrieval with specialized models without confusing dynamic knowledge with learned behavior

• Build rigorous LLM evaluation workflows using golden sets, challenge tests, hallucination and faithfulness analysis, human assessment, and regression gates

• Apply quantization, distillation, batching, caching, and context management for practical LLM model optimization

• Engineer reliable language model deployment across local, cloud, and edge environments

• Design production APIs, model routing, verification, security, graceful degradation, and selective LLM fallback

• Detect data drift, domain drift, retrieval failures, quality degradation, and rising production costs

• Build controlled feedback loops, release gates, monitoring systems, and reusable engineering decision frameworks

• Scale from one specialized model to a governed portfolio of production-ready AI capabilities

The question is no longer:

“Which model is the most powerful?”

It is:

“What is the smallest and simplest AI system that can reliably satisfy the required quality and operational constraints?”

Whether you're building an enterprise assistant, technical-support system, financial extraction model, engineering copilot, cybersecurity classifier, private knowledge interface, or another specialized AI application, this book gives you a practical path from model selection to production operation.

Don't just fine-tune a model. Engineer the complete system around it.
