A strong Next.js portfolio shows polished pages. A useful hiring conversation also covers what happens after deployment: how the application is monitored, updated and recovered when something fails.
Describe the existing environment
Tell candidates whether they are improving an existing site or building a new one. Share the framework version, hosting approach, key integrations and the user journeys that must remain unchanged. Never put production credentials in a public project description.
Ask for experience with the kind of work you need. A content-heavy website, a marketplace and an internal reporting tool have different priorities even when they share a framework.
Ask for evidence of delivery
Request a walkthrough of a project the developer is permitted to discuss. Ask how they handled loading states, forms, authentication, server errors and mobile layouts. Invite them to explain one trade-off rather than simply naming technologies.
Useful questions include:
- How will you preserve existing URLs and payment callbacks?
- Which changes require a database migration?
- What will be tested before release?
- How would our team roll back a failed deployment?
Define acceptance beyond appearance
Include representative routes, devices, account states and network conditions. Establish a performance baseline before work starts. Google's Web Vitals guidance provides common user-experience measures, but a synthetic score alone does not prove the site works for customers.
Require source files, deployment instructions, an environment-variable inventory without secret values and a record of changed dependencies. Confirm who owns the hosting and third-party accounts.
For an existing WorkFry-style marketplace, regression checks should cover signup, project posting, checkout and administrative permissions. Find development specialists with a clear list of those protected flows.
