Backend data layer
The domain model, its indexes and constraints, and state that survives concurrency.
What we build
Modelling the data the business actually runs on, the indexes and constraints that keep it correct and fast as it grows, and durable state that behaves when two things happen at once — the difference between a system that works in a demo and one that works on a busy Monday.
What you get
- Schema and migration files defining every entity in the agreed data model
- Indexes and constraints applied by migration, each named with the query it serves
How the work unfolds
- Model the domain data
- Ensure indexes and constraints in code
- Build durable state with concurrency safety
What shapes the price
Before you see a number, our scoping conversation asks:
- Roughly how many kinds of records will the system keep track of — customers, orders, messages, that sort of thing? Each entity is modelled, constrained and indexed.
- Will several people be working on the same records at the same time? Concurrency safety is real engineering a single-editor system can skip.
How an engagement starts
This work builds on Backend API foundations, so scope, boundaries and constraints are agreed before anything is built.
