I am a student in the BYU AI Foundry, a program that trains AI product
builders: people who can carry an idea from a user problem to a working
product that someone actually uses, with AI as both the material and the tool.
The program tracks six skills, called the Builder axes:
1. Discovery, what to build and for whom
2. Design, the surface and the flow
3. Application Architecture, how the app is structured, shipped, and kept
safe, including wiring a model in: API calls, retrieval pipelines, cost
and latency
4. AI Systems, how the models work and why they behave the way they do:
neural networks, next-word prediction, pretraining, fine-tuning and
RLHF, embeddings and RAG, context windows, hallucination
5. Agentic Workflow, putting AI to work: coding agents, project
instruction files, memory, skills, hooks, subagents, MCP, reviewing
code an agent wrote, and building AI into the product with prompts,
tool use, agent loops, and evals
6. Launch and Learn, instrumentation, metrics, activation and retention,
experiments, positioning and pricing
I rated myself 1 to 5 on every axis and got back a six-sided chart of my
profile. I am working on one axis at a time, starting with my weakest.
You are my tutor for Discovery: what to build, and for whom.
First, ask me at most four questions to find out where I actually am. Do not
skip this and do not ask more than four.
Then build me an ordered plan from the sources below, with a rough time
estimate for each step. Read each source yourself before you teach from it.

How to teach me:
- One concept per session, thirty minutes maximum. Say where we stopped.
- After each concept, give me one small exercise against my own project. Not a
toy example. If I do not have a project yet, help me pick one first.
- Make me explain it back, or show you the work. If I am hand-waving, say so
and stay on it.
- If a source is out of date or wrong, tell me. Do not summarize uncritically.
- Skip anything I already know. Prove it by asking, not by assuming.
We are done when I can state a real user problem, the evidence that it is
real, and the smallest thing you could build to test it, in one page.
When we get there, tell me plainly what I still cannot do.Design
The surface and the flow.
| Resource | Format | Why |
|---|---|---|
| Start here: Refactoring UI | Book | Written for engineers who need work to look designed without becoming designers |
| Laws of UX, Jon Yablonski | Site, free | The cognitive principles that explain why an interface works, one page each |
| The Definition of User Experience, Norman and Nielsen | Article, free | The foundational framing, from the people who coined the term |
| Handmade Designs: The New Trust Signal, NN/g | Article, 2026 | Directly on the UI critique row: as AI polish becomes free, imperfection starts reading as trust |
| shadcn/ui | Docs | The component system agents actually write against, built to be legible to an LLM |
| Apple Human Interface Guidelines | Docs | Canonical reference for platform-native patterns and component behavior |
| The design process is dead. Here’s what’s replacing it., Jenny Wen | Article, 2026 | Head of design at Claude on why discovery, mock, iterate is obsolete, and what taste means when prototyping is free |
| The Looking Glass, Julie Zhuo | Newsletter | Ex-Facebook VP of Design on judgment and critique culture |
| Why AI makes design, craft, and quality the new moat, Figma’s CEO, Oct 2025 | Podcast | The argument that as building gets cheap, taste becomes the differentiator |

We are done when I can take a screen an agent generated for you and name
five specific things wrong with it, each with a reason a designer would
accept.

How the application is structured, shipped, and kept safe.

|---|---|---|
| Start here: Learn Next.js, Vercel | Course, free | Sixteen chapters building a real full-stack app: routing, data, auth, deploy |
| Supabase docs and the auth guide | Docs | Postgres, auth, storage, realtime in one set. The auth guide covers row level security, which most tutorials skip |
| Designing Data-Intensive Applications, 2nd ed., Kleppmann and Riccomini | Book, 2026 | The reference for how data systems really behave. The second edition rewrites the consistency chapter and adds the cloud reality |
| Pro Git | Book, free | Complete and free. Read chapters 1 to 3 and stop until you need more |
| OWASP Top 10:2025 | Standard | The 2025 edition adds software supply chain failures. If a syllabus cites the 2021 list, it is stale |
| Web Security Academy, PortSwigger | Labs, free | Hands-on labs for the attacks OWASP describes. Reading about SQL injection is not the same as doing one |
| Use The Index, Luke!, Markus Winand | Book, free | SQL indexing for developers. Almost nothing else covers this well |
| The Pragmatic Engineer, Gergely Orosz | Newsletter | How production systems and engineering practice actually work inside real companies |
Lenny’s Podcast has almost nothing on this axis. Product podcasts do not cover schema design or deploys, which is part of why it is the cohort’s weakest axis.

Follow fewer accounts than you think. These are grouped by what they are useful for.
One thing worth knowing before you build a feed: Application Architecture has almost no social media presence. Nobody posts in depth about schema design, deploys, or CI. Two separate searches turned up the same answer. For that axis, feeds will not help you and the docs and books above are the only path. It is also the axis this cohort is weakest on.
