I will test and harden your web app with playwright and API checks

Japan

I speak Japanese, English

API Automation and QA Developer

I am a software developer experienced in web development and quality assurance. I build reliable REST APIs, Python automation, Laravel and Vue features, data-processing workflows, and automated tests....
About this Gig

I test web applications through the boundaries real users and integrations depend on: browser journeys, HTTP APIs, validation rules, authorization, and state transitions.


You receive actionable evidence:

risk-based test scope

expected versus actual behavior

clear reproduction steps

severity and business impact

screenshots, traces, or response evidence

release-risk summary

optional Playwright and API regression checks


My public QA reference includes a verified 107-check run, 12 structured manual cases, two real defects found and fixed, and a negative-test harness that detected all 6 seeded defects. Browser automation is used only for authorized testing of the application in scope.


Please provide a test or staging URL, supported browsers, important roles, critical journeys, known exclusions, and test accounts with anonymized data. I can work asynchronously without video meetings.
