Model
Entities, relationships and the invariants the system must never break.
Dashboards, portals, internal tools and customer-facing platforms — built type-safe end to end and structured so the fifth engineer to touch it moves as fast as the first.
Signals
Most applications do not fail because the framework was wrong. They fail because the data model was decided in a hurry, the boundaries were never drawn, and every new feature had to be threaded through six places. We start with the model and the boundaries, then build outwards. It is slower for a fortnight and considerably faster for the following two years.
Your team is maintaining a prototype that was never meant to reach production.
Adding a feature now touches half the codebase and nobody can predict the blast radius.
The interface is fast on the demo account and slow on the real one.
Sequence
Entities, relationships and the invariants the system must never break.
Routing, auth, permissions and deployment working end to end on day one.
Features built against the skeleton, deployable every week.
Load, edge cases, error states, monitoring and the handover document.

Questions
Usually, yes. We start with a short audit — a few days — and come back with an honest answer about whether extending it or replacing part of it is the cheaper path over eighteen months.
