Screen Reader UX, Vertical Slice Architecture, and AI Agents as Users
Published on 15.04.2026
The Invisible Layer of UX Most Designers Ignore
TLDR: Screen readers translate your UI into a linear stream of announced roles, names, and states. Designers who only think visually are shipping broken experiences to assistive technology users. The fix doesn't require learning to code — it requires thinking in "role, name, state" while you design.

Minimum Viable Product: Definition
TLDR: An MVP is a structured experiment, not a stripped-down product. The usability of your MVP matters just as much as its functionality — if the interface is confusing, you're testing the wrong thing. Define clear hypotheses before you build anything.

Commercial vs Internal Products
TLDR: Internal products are hard, but commercial products are harder because you have to win in an open marketplace. With an internal product, users can't choose a competitor. With a commercial product, you need to be so much better that people will actively switch from whatever they use today.

Vertical Slice Architecture in Node.js
TLDR: Organize code by use case, not by technical layer. Each feature gets its own folder containing handler, validation, types, and tests. Adding a feature means adding a folder, not touching five different directories.

AI Agents as Users
TLDR: AI agents now interact with digital interfaces alongside humans. They have goals, encounter interfaces, and succeed or fail based on how those interfaces are built. Accessibility fundamentals — semantic HTML, clear labels, logical hierarchy — are exactly what agents need too.
Designers Will Never Have Influence Without Understanding How Organizations Learn
TLDR: What teams are shipping via vibe coding aren't prototypes — they're demos. Demos test whether stakeholders like what they see. Prototypes test something you don't know yet. Confusing the two means nothing gets learned.
