Most Python portfolios look the same: a to-do app, a Titanic notebook, and not much else. Hiring managers screening backend and AI candidates want something sharper, and well-chosen FastAPI projects<\/strong> deliver it. The framework has moved from side-project favourite to production default, with the 2025 Stack Overflow Developer Survey showing FastAPI up five percentage points in a single year.<\/p>\n\n\n\n

This guide gives you 15 FastAPI projects<\/strong> with source code, ordered from beginner to advanced, plus a clear way to present them. New to the language? Start with Scaler’s Python developer roadmap<\/a>. If you are still asking what is fast api<\/strong>, the next section answers it in under a minute.<\/p>\n\n\n\n

<\/span>What Is FastAPI and Why Build<\/strong> FastAPI Projects<\/strong> With It?<\/strong><\/span><\/h2>\n\n\n\n

According to the official FastAPI documentation, FastAPI is a modern Python web framework for building APIs. Created by Sebasti\u00e1n Ram\u00edrez and released in 2018, it runs on Starlette for async request handling and uses Pydantic to turn type hints into validation and OpenAPI docs, so a basic FastAPI example<\/strong> needs only a few lines.<\/p>\n\n\n\n

Python itself rose about seven points to roughly 58% in the same survey, and FastAPI has become a common choice for model serving and AI backends. Netflix built its incident-management tool Dispatch on it. For you, that means FastAPI projects<\/strong> double as proof of API design, async Python, databases and deployment in a single repository.<\/p>\n\n\n\n

Here is the smallest useful FastAPI example<\/strong>. Save it as main.py, run fastapi dev main.py, and open \/docs for interactive Swagger UI.<\/p>\n\n\n\n

from fastapi import FastAPI<\/p>\n\n\n\n

from pydantic import BaseModel<\/p>\n\n\n\n

app = FastAPI()<\/p>\n\n\n\n

class Task(BaseModel):<\/p>\n\n\n\n

title: str<\/p>\n\n\n\n

done: bool = False<\/p>\n\n\n\n

@app.post(“\/tasks”)<\/p>\n\n\n\n

def create_task(task: Task):<\/p>\n\n\n\n

return task<\/p>\n\n\n\n\nScaler Carousel<\/title>\n\n<!-- Plus Jakarta Sans Font -->\n<link href=\"https:\/\/fonts.googleapis.com\/css2?family=Plus+Jakarta+Sans:wght@400;500;600;700&display=swap\"

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Start here to learn routing, validation and databases. If Python syntax still slows you down, take Scaler’s free <a href=\"https:\/\/www.scaler.com\/topics\/course\/python-for-beginners\/\">Python for Beginners course<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>To-Do List API<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Build full CRUD endpoints with Pydantic models, path and query parameters, and proper status codes, first in memory and then on a database. It teaches request validation, which every backend interview touches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source code: The official FastAPI tutorial walks through the same endpoints step by step.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>URL Shortener<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Generate short codes, redirect users, and cache hot links in Redis. Add JWT login and rate limiting to turn a weekend build into a service that handles abuse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source code: FastURL uses FastAPI, PostgreSQL, Redis, and JWT.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Weather or Currency API Wrapper<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Call a third-party API with httpx, cache the responses, and expose clean endpoints. You practise async calls, timeouts and error handling without needing a database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source code: fastapi-cache by long2ice supplies the caching layer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Expense Tracker With SQLModel<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Store expenses, filter by category and return monthly totals. SQLModel, from the FastAPI author, merges SQLAlchemy and Pydantic models into one class. Refresh <a href=\"https:\/\/www.scaler.com\/topics\/dbms\/\">DBMS fundamentals<\/a> if joins and indexes feel rusty.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source code: SQLModel docs include a FastAPI walkthrough.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Inventory Management API<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Create products and stock levels, then add a paginated <strong>fastapi list<\/strong> endpoint with search and sorting. Pagination is an interview staple and a common gap in beginner repos.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source code: fastapi-pagination by uriyyo handles the heavy lifting.<\/p>\n\n\n<meta
