Web app and dashboard development

How we approach it

The row comes before the layout.

1. 01

   Start from the record

   Each screen names the table or document it shows, the filter it applies, and how fresh that data is allowed to be. A cache is a copy. The database remains the record.

2. 02

   Put the role on the row

   Login is not the boundary. We write the access rule where the data lives, so a portal cannot render a row the database would refuse. Admin, operator, and customer see different sets.

3. 03

   Keep a dense screen usable

   Lists virtualize. Heavy updates go through a transition so the page stays responsive. Keyboard, focus, and the empty and error states are part of the screen, not a later pass.

4. 04

   Cache only what may be stale

   A route is cached for how often its data changes. A write names the tag that must refresh. We check that behavior, and Core Web Vitals, before the page ships.
