Why we model the domain before writing controllers

Most projects we inherit start the same way: someone sketched screens, then wrote controllers to match. It works for the demo. Two years later, every new feature fights the data model underneath.

We do the opposite. Before we write a controller, we map the domain — the entities, the rules, and the transitions your team already uses in spreadsheets, chat threads, and memory.

What we map first

• Actors and permissions — who can create, approve, cancel, or only view?
• State transitions — a booking moves from requested → confirmed → completed. What invalidates that path?
• Edge cases — double-bookings, partial payments, after-hours rules, cancelled sessions that free a slot.
• Integrations — what must leave the system via API, webhook, or export?

That map becomes the brief we build against — and argue with when scope creeps.

What this saves you

When the domain is clear, Filament admin panels, customer-facing Nuxt pages, and background jobs all speak the same language. You spend less time patching mismatches between "what the UI shows" and "what the database allows."

It also makes estimates honest. We can tell you which modules are straightforward and which ones hide regulatory or operational complexity — before you commit budget.

When to skip this

If you need a two-page marketing site or a throwaway prototype, full domain modeling is overkill. We will say that directly.

If you are replacing spreadsheets that run a venue, clinic, or operations team — skipping this step is how you buy a second rebuild in eighteen months.

What we need from you

A walkthrough of how work happens today. Sample exports, screenshots of current tools, and the exceptions your team handles manually. That is enough to start.
