# AI Engineer Pathway (LLM App Builder)

> Build, deploy, and secure real-world LLM applications. Mentor-led pathway covering prompt engineering, RAG systems, AI security, and production deployment. Exam-aligned with Azure AI, AWS ML, and Google ML certifications.

## Outcomes

- Design and engineer LLM-powered applications using modern AI APIs
- Apply structured prompt engineering and tool-based workflows
- Build Retrieval-Augmented Generation (RAG) systems using vector databases
- Develop secure backend services for AI applications
- Deploy containerised AI systems to cloud platforms
- Apply AI security, privacy, and governance controls
- Deliver a complete, portfolio-ready AI engineering project

## Stages

1. **Engineering Foundations for AI** — Python for AI application development, API integration, async processing, and data flows. Practical AI and machine learning concepts for engineers.
2. **LLM Engineering Fundamentals** — Prompt engineering for production environments. Working with leading LLM APIs. Token usage, performance optimisation, and cost control. Embeddings and semantic search foundations.
3. **Building LLM Applications** — Chatbots, copilots, and internal AI tools. Retrieval-Augmented Generation (RAG) design patterns. Document ingestion from files, databases, and APIs. Orchestration and agent-based workflows.
4. **Backend Engineering and Deployment** — API development for AI services. Authentication, rate limiting, logging, and monitoring. Docker and containerised deployments. Cloud deployment aligned with AWS, Azure, and GCP environments.
5. **AI Security, Risk, and Governance** — AI threat models and misuse scenarios. Prompt injection and data leakage risks. Secure AI architecture and guardrail implementation. Privacy-aware AI design and GDPR alignment. Monitoring, audit trails, and operational controls.
6. **Capstone Project** — End-to-end LLM application build with realistic business use case. Architecture design and technical documentation. GitHub repository and working demo. Portfolio review and career guidance.
