Hire a web app developer around a workflow, not a page count. The right person should connect the interface a user sees with the data, rules, integrations, and deployment behind it.
Begin with the user flow
Write the task in one sentence before discussing a framework: who arrives, what information do they need, what decision or action do they take, and what changes after it succeeds? This separates a working application from a collection of attractive screens. The developer should be able to name the happy path as well as empty, loading, permission, validation, and error states.
Review the application boundary
Frontend
Ask how the interface will make the main state and next action clear on desktop and smaller screens. Useful evidence includes accessible HTML, responsive layouts, clear form validation, and sensible handling of slow data. A polished screenshot is useful, but it does not show whether the interaction is usable.
Backend and data
Ask what records exist, who can read or change them, and what must be recorded for the workflow to make sense. The answer should explain data ownership and validation in plain language. If sensitive actions exist, ask how authorization is enforced beyond hiding a button.
Integrations
For every API, webhook, payment, or data source, agree on inputs, expected output, failure behavior, and account ownership. A connection that only succeeds in a happy-path demo is incomplete. The application should explain what happened when a dependency is delayed, unavailable, or returns malformed information.
Evidence and scope to ask for
- A walkthrough of a live application or code sample that shows decisions, not only visual polish.
- An explanation of a difficult state, migration, or integration and how it was handled.
- A proposed first workflow with explicit boundaries and assumptions.
- A plan for repository access, environments, deployment, and handoff.
- How changes will be reviewed and tested before release.
Use a short written boundary: the user, main task, records required, integrations required, acceptance conditions, and what is deliberately out of scope. Plan handoff early. The client should control the repository, hosting, data service, and key integrations. Document the environment variables and release steps. Deployment is part of the experience because a feature is only useful when the right people can reliably reach it.
Keep the review grounded
Use the proposed workflow as the review tool throughout the engagement. Each update should make it easier to inspect the path a user takes, the information shown, and the outcome recorded. This makes scope decisions concrete and helps catch gaps before a late visual review or a deployment deadline exposes them.
Review the system, not only the screens
A web application is a workflow across interface, server behavior, data, and integrations. During evaluation, walk through one realistic scenario from sign-in to a recorded outcome. Ask what the user sees while data loads, what changes when a request fails, and which roles can take each action. This reveals whether the proposal has a complete boundary or merely a collection of screens.
Make handoff explicit
Before work starts, agree on repository access, hosting ownership, environment variables, data migration responsibility, and a short deployment checklist. A useful handoff leaves the next maintainer able to run the application, understand the key flows, and locate the services it depends on. It should also identify the remaining operating decisions, such as who reviews errors, approves access, and makes the next scope call after people begin using the workflow.
