With AI you are already making design decisions.
Courses I through IV teach you what real systems like Instagram, Stripe, and Netflix are made of, using the same seven building blocks.
Course 0 is the $99 on-ramp: it teaches you to command an AI agent on real work. Courses I-IV then build the judgment to evaluate what it built.
The same shape, four times: video lessons, two hands-on labs, feedback on your answers, one design challenge.
The foundation: the seven parts every system is actually made of, and the three outside forces that act on them (people, other companies' services, and time). You learn them by designing a link shortener from MVP through viral growth to monetization.
Instagram, Netflix, YouTube: the read-heavy systems everyone uses. Five progressive case studies, from a blog to semantic search.
Slack, Discord, WhatsApp: systems where milliseconds matter. Five progressive case studies, from a social feed to AI chatbots to video conferencing.
Stripe, Shopify, Salesforce: systems where a wrong design is a double charge. Four progressive case studies, from e-commerce to dynamic pricing to peer-to-peer payments.

In Anthropic's trial, the AI group scored 17 points lower on a quiz about their own code. That quiz also measured debugging, code reading, and the judgment call on whether AI-written code follows the right design patterns. That's what Courses I through IV teach: the seven building blocks as the vocabulary for judging what the AI built.
A CHI 2026 study of ten junior and ten senior engineers found the same shape from the other side: seniors keep control by arriving with a plan and delegating only what fits, while juniors on unfamiliar code swing between over-reliance and avoidance. (Feng, Yun, Wang, "From Junior to Senior," CHI 2026.)
Engineers who already ship code with an AI agent and want to know whether the design underneath it holds up.
No. Either order works. Course 0 teaches you to command an AI agent on real work; Courses I-IV teach you the seven building blocks, so you can tell a good design from one that will break. Most people take Course 0 first, then Courses I-IV, but nothing here requires it.
You submit your own design decisions for each case study, and you get feedback on the decisions you actually made: which ones held up, and which ones a senior engineer would have questioned.
Lifetime access. The courses are self-paced: work through them on your own schedule, Course I first, then II, III, and IV in order.
