Front-end application
A responsive, accessible React or Next.js interface with real states for loading, empty, and error.
Capability 02
Web applications built from interface to database.
React and Next.js interfaces on Python and Node services, with authentication, payments, and a deployment that someone other than the author can operate.
What this covers
One person accountable for the whole request.
Useful when the interface, the API, and the database have to agree with each other. One person building across that boundary means a screen and the data behind it change together, instead of being negotiated between two teams over several rounds.
Typical problems addressed
- A business runs on spreadsheets and needs an application people can actually use.
- A storefront or portal needs accounts, a catalogue, and a working checkout.
- An internal tool needs to read from the same data the reporting already uses.
- An existing site works but cannot be extended, deployed, or handed over safely.
Typical deliverables
The application and everything under it.
Scope is set by the audience, the integrations, and who maintains it afterwards.
Backend API
Python or Node services with a documented contract and server-side validation.
Database
A SQL schema designed for the queries the product actually runs, with migrations kept in version control.
Accounts and access
Registration, sign-in, token handling with refresh, and role-appropriate permissions.
Payments and integrations
Checkout and third-party services wired in so a failed call is handled, not silently lost.
Deployment
Environment configuration, a release path, and notes on running and rolling back.
Workflow
Data first, then the screens on top.
Building in this order avoids interfaces that promise what the data cannot support.
Scope
Agree the journeys the product must support and what each screen has to answer.
Model
Design the schema and API contract so the interface has something firm to build on.
Build
Implement service and interface together, one complete journey at a time.
Release
Deploy, check the real states, and document how to operate and extend it.
