Learn a step-by-step roadmap to become a GenAI engineer, building intelligent software with Python, FastAPI, and real architecture

intermediate Published 20 Jun 2026
Action Steps
  1. Build a naive bot using Python and FastAPI to understand the basics of GenAI development
  2. Implement structured outputs and conversation memory to enhance the bot's capabilities
  3. Create prompt templates and output parsers to improve the bot's understanding and response generation
  4. Integrate a knowledge base using RAG to enable the bot to retrieve and use external information
  5. Use tool calling to extend the bot's functionality and interact with other systems
  6. Develop a LangGraph agent to create a more sophisticated and autonomous GenAI system
Who Needs to Know This

This roadmap is beneficial for software developers looking to transition into GenAI engineering, and for teams working on AI-powered projects who need a structured approach to building intelligent software.

Key Insight

💡 Building intelligent software requires a structured approach, starting from a naive bot and incrementally adding capabilities such as conversation memory, prompt templates, and knowledge base integration.
