I’m 19 and currently learning backend development and AI tools. Instead of just watching tutorials, I wanted to understand how AI APIs actually work in a real backend. So I built a small AI SaaS starter template using FastAPI and OpenAI. The goal was to learn how to structure an AI backend that could be extended into a real SaaS product. What I implemented: • FastAPI backend structure • OpenAI API integration • simple AI generation endpoint • basic modular project layout (api, services, models, utils) Things I learned while building it: Structuring AI services separately makes the backend easier to maintain. Handling API keys and configuration properly is important when working with AI APIs. Even a small AI backend needs a clean architecture. I’m still improving the project and learning more about AI backend design. If anyone has suggestions on how to structure AI services or improve the architecture, I would really appreciate feedback… submitted by /u/Sea-Literature6315
