Today Quincy Larson interviews Landon Gray. Hes a software engineer who worked at agencies for years. Then he taught himself AI assisted software development. And now hes helping other devs do the same.
Landons 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.

2. Learn how to properly test your software and ensure it doesnt break when you add new features. Prolific freeCodeCamp instructor Beau Carnes teaches this course. Hell introduce you to the Testing Pyramid and show you how to balance fast unit tests against complex end-to-end user journeys. Youll 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 dont 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.
