Your app looks ready in a demo. Can a new customer actually sign up, complete the main task and find their saved work after returning? I test the journeys your launch depends on and give your developer a clear, reproducible list of what needs fixing.

This service is for founders and teams preparing a web app for its first users or a significant release. I work through an agreed set of customer and staff journeys, checking the result behind each screen: whether data saved, access rules held, navigation worked and failures left the user with a usable next step.

Testing follows your product's risks. That might include expired links, interrupted submissions, duplicate clicks, empty states, a direct page load, or a user attempting an action outside their role. We agree the relevant cases and browser coverage before work starts.

On a headless Next.js/WordPress project, I traced valid published pages returning 404 and missing pages showing a 404 screen while returning HTTP 200. Another developer implemented the corrections; I independently checked the corrected behavior on specific deployment builds and production. That distinction matters: a screen looking right does not prove the underlying behavior is right.

You receive a concise release assessment, evidence-backed defects your developer can reproduce, and priorities based on customer impact. After your team makes the agreed corrections, I run one focused retest and update the findings. You can see what passed, what remains broken and what was outside the checked scope.

An agreed test scope: the critical journeys, user roles, supported browser conditions and expected results we will check.

A reproducible defect report: steps, expected and actual behavior, affected build, severity and supporting screenshots or recordings where useful.

Customer-impact priorities: blockers separated from important fixes and improvements that can wait.

A release assessment: a concise summary of checked behavior, open risks and anything blocked by missing access or unavailable integrations.

One focused retest: re-check the agreed corrected defects on one replacement build, then update their status and flag any regression observed within those checks.

For a small app, a useful first engagement is three critical journeys across up to two user roles. For example: sign-up and access, completing the core task, and reviewing or managing the result.

We agree the test accounts, browser coverage, candidate build and retest window before the quote. This keeps the work focused on the behavior that matters for your release. Larger apps can be tested in phases.

You show me the app, the intended users and the release goal. We choose the journeys and failure cases that matter, define their expected results and agree the testing environment.

I test the agreed release candidate with representative accounts and data. I record each failure with enough detail for a developer to reproduce it, including the build where it happened.

You receive the defect report and release assessment. I explain which issues prevent a customer from finishing a task, which create data or access risks, and which can reasonably wait.

Your developer provides a replacement build. I run the included retest against the agreed defects and return an updated status summary. Implementation can be quoted separately if you want me to make the fixes too.

A working staging or preview URL and the specific build you want tested.

A brief description of your users, the app's main purpose and what must work at launch.

Test accounts for the agreed roles, representative test data and any required invitation or reset links.

Expected behavior for the selected journeys, including relevant business rules.

Access to relevant logs or records where needed to verify the result behind the interface.

A developer contact and an agreed date for the retest build.

I also built RoutePlay, TypeScript/Chromium tooling that compares server HTML, fresh browser loads and real in-app navigation against configured expectations, with evidence captured for failed checks.
