AI Engineering Practice Projects​

Project 1: Build a Chatbot with Memory​

Use the OpenAI API to build a chatbot that remembers conversation history. Practice: API calls, message arrays, system prompts, and streaming responses.

Project 2: Build a RAG System​

Create a system that answers questions about your own documents. Practice: text chunking, embedding generation, vector similarity search, and prompt augmentation.

Project 3: Build an AI Agent with Tools​

Create an agent that can search the web, read files, and execute code. Practice: tool definitions, agent loops, and error handling.

Project 4: Build an MCP Server​

Create a Model Context Protocol server that exposes your data to AI assistants. Practice: protocol implementation, tool definitions, and resource exposure.

How to Practice AI Engineering Effectively​

  1. Start with APIs — learn to call OpenAI, Anthropic, or Mistral APIs before building complex systems
  2. Build incrementally — start with a basic chatbot, add memory, then add tools, then add RAG
  3. Test with real data — use your own documents, not toy datasets
  4. Deploy something — put an AI app online so you can show it to employers or clients
