What happens when the model CAN'T fix it? Interview w/ software engineer Landon Gray [Podcast #213]

Today Quincy Larson interviews Landon Gray. He's a software engineer who worked at agencies for years. Then he taught himself AI assisted software development. And now he's helping other devs do the same. Landon's famous for proving that RAG pipelines can be written in Ruby and popularizing Ruby as a language for building machine learning projects. He works as an AI Engineer at a enterprise software company and runs a popular newsletter. We talk about: - How Large Language Models are just the raw fuel, and harnesses are the real engine to get things done - Why building your professional network is so helpful for finding clients and landing job interviews - Why Landon helped port Python machine learning libraries to Ruby, and why he thinks that – now that AI is just an API call away – the Ruby ecosystem is better-positioned than ever. Support for this podcast comes from the 10,113 kind folks who donate to our charity each month. Join them and support our mission at https://donate.freecodecamp.org Get a freeCodeCamp tshirt for $20 with free shipping anywhere in the US: https://shop.freecodecamp.org Links from our discussion: - Landon's Substack newsletter: https://landongray.substack.com Community news section: 1. freeCodeCamp just published a new YouTube course that will teach you beginner Front-end Development skills like HTML, CSS, and JavaScript. You can code along at home and build a variety of projects: your own interactive quiz game, a currency converter app, and even a Trello-style kanban board. Along the way you'll learn how to use APIs and local storage to extend the functionality of these bite-sized apps. (12 hour YouTube course): https://www.freecodecamp.org/news/build-19-web-dev-projects-using-html-css-javascript/ 2. Learn how to properly test your software and ensure it doesn't break when you add new features. Prolific freeCodeCamp instructor Beau Carnes teaches this course. He'll introduce you to the Testing Pyramid and show you how to balance fast unit tests against complex end-to-end user journeys. You'll also learn how to automate some of this testing using an open source library called Playwright and an LLM testing tool. (1 hour YouTube course): https://www.freecodecamp.org/news/software-testing-with-playwright/ 3. More and more apps are relying on probabilistic LLM output alongside deterministic API calls. This makes life harder for devs who now need to ensure that hallucinations don't escape to end users. freeCodeCamp just published this advanced observability tutorial that will teach you emerging best practices and architectural patterns for dealing with this. (40 minute read): https://www.freecodecamp.org/news/build-end-to-end-llm-observability-in-fastapi-with-opentelemetry/ 4. Learn how to containerize your MLOps pipelines. This tutorial is the result of hard-won deployment wisdom. The author spent three weeks debugging a Python library error due to dependency conflicts. His eventual answer: containerize entire project with Docker. This tutorial will show you how to structure your containers with multi-stage builds. You'll also learn how to set up experiment tracking with MLflow, versioning with DVC, GPU passthrough, and other advanced techniques. (40 minute read): https://www.freecodecamp.org/news/containerize-mlops-pipeline-from-training-to-serving/ 6. Today's song of the week is 2006's Everybody by UK producers Basement Jaxx. If you're familiar with their work, you know you're in for a psychedelic yet silly romp. Between the spoons, bongos, and swooning chorus the song feels like it's held together with duct tape but it works. https://www.youtube.com/watch?v=OrMot81VE8g

Python FastAPI Tutorial (Part 9): Frontend Forms - Connecting JavaScript to Your API

In this video, we'll be adding interactive frontend forms that connect to our FastAPI backend. Up until now, our web pages have been read-only, but we'll change that by using JavaScript and the Fetch API to create, edit, and delete posts directly from the browser. We'll use Bootstrap modals for our forms and feedback messages, keeping users on the current page instead of navigating them away. This tutorial focuses on the API interaction itself and how the frontend sends data to our endpoints and handles responses. Let's get started...

Python FastAPI Tutorial (Part 8): Routers - Organizing Routes into Modules with APIRouter

In this video, we'll be learning how to organize our FastAPI application using APIRouter. As our app has grown throughout this series, our main.py file has become long and difficult to maintain. We'll fix that by creating a routers directory and splitting our API routes into separate modules—one for users and one for posts. This is a common pattern in real-world FastAPI development and is similar to Blueprints if you're coming from Flask. By the end of this video, you'll know how to structure your FastAPI projects for better maintainability and scalability. Let's get started...

Python FastAPI Tutorial (Part 7): Sync vs Async - Converting Your App to Asynchronous

In this video, we'll be learning about synchronous versus asynchronous in FastAPI. We'll cover when you should use async routes, when you should stick with synchronous routes, and then we'll convert our entire application from sync to async. This includes updating our database configuration to use async SQLAlchemy with aiosqlite, converting all of our routes to use async/await, handling eager loading for relationships, and updating our exception handlers. By the end of this tutorial, you'll understand when async actually provides benefits and how to implement it correctly in your own FastAPI projects. Let's get started...

Python FastAPI Tutorial (Part 5): Adding a Database - SQLAlchemy Models and Relationships

In this Python FastAPI tutorial, we'll be learning how to add a database to our FastAPI application using SQLAlchemy. Up until now, we've been storing our data in a Python list in memory, which resets every time the server restarts. We'll fix that by connecting to a real SQLite database and setting up SQLAlchemy models with relationships between users and posts. We'll also look at why we use separate SQLAlchemy models and Pydantic schemas, and how to use FastAPI's dependency injection to manage database sessions. By the end, you'll have a solid foundation for database-driven FastAPI applications that you can later scale up to Postgres or MySQL. Let's get started...
