Enterprise AI systems architecture — a free, bilingual course

AI Architect Trainer is an independent, free training platform for engineers and architects who build systems around large language models, rather than only prompting them. Every lesson, question and flashcard exists in both Ukrainian and English. There is no paid tier.

Four tracks

Enterprise Intelligence Architecture (E1–E8)

The platform a model runs inside, across four layers: the data fabric and distributed compute beneath it, lakehouse storage and incremental views, the semantic ontology and domain model that give data meaning, entity resolution and knowledge graphs, attribute-based access control and policy enforcement, provenance and lineage for compliance, decision intelligence, and consensus between reasoning agents. Each lesson names the peer-reviewed papers it derives from.

Claude engineering (L1–L14)

The working surface of the Claude ecosystem: the Messages API, tool use and tool design, Claude Code, the Model Context Protocol, the Agent SDK, extended thinking, computer use, deployment on Bedrock and Vertex, prompt caching, the batch API and evaluation harnesses. Every module ships lessons, cheat sheets, spaced-repetition flashcards, interactive simulators and hands-on labs.

CCA-F exam preparation

Independent study material for Anthropic's Claude Certified Architect — Foundations exam, mapped to the five published domains: agentic architecture and orchestration, tool design and MCP integration, Claude Code configuration and workflows, prompt engineering and structured output, and context management and reliability. Scenario questions, a timed mock exam and a weak-spot review loop.

Starter 0→1

For people arriving without a background in this: everyday workflows, prompt patterns that generalise, artifacts, and an honest look at what tokens cost.
