Tech Literacy

Feb–Apr 2026WebLive

Tech Literacy is an online course I built that teaches computer-science fundamentals to people who build with AI but never learned to code.

It covers 14 layers, from how a computer works to shipping AI products, in 278 lessons of short readings, videos and quizzes, with progress tracking and a daily streak.

I built it because I was that student: I could direct AI to build apps, and I wanted to understand exactly what I was asking it for.

Fourteen layers, foundations first

Building by directing AI works until something breaks, and then you need to know what a server, a DNS record or an API key actually is to tell the AI what's wrong. Most CS courses teach that to future programmers. I wanted the version for people like me, who build through AI and need the concepts more than the syntax.

So the course is ordered like a stack: the machine, how software is built, how code works, the internet, how apps are structured, how services connect, deployment and security, then six layers on AI and product, from how models work and prompt engineering to agent systems and shipping. Each layer builds on the one before, and the dashboard shows what's next and how much is left.

Short readings on one idea each

Most lessons are three-minute readings on a single idea. The DNS lesson walks through what happens when you type a domain, step by step, then the record types you'll touch when you point a domain at an app. Videos from Fireship, a popular programming channel, fill in where a visual explains it better.

A Tech Literacy reading titled 'DNS: The Internet's Address Book', with a numbered list of how DNS resolution works and the common record types.

Quizzes every few lessons

Every few lessons, a five-question quiz checks what stuck, with instant feedback and a short explanation for each answer. At the end of a layer, Claude writes a fresh unit test every time, tracks which subtopics I missed and links me back to those lessons.

A Tech Literacy quiz question, 'What is the internet at a physical level?', with the correct answer checked and an explanation below.
