QA Engineer Playwright | API Testing | Browser DevTools Debugging

About Me I'm a QA Engineer with 6+ years of experience delivering test coverage for Retail SaaS, mobile apps, and agency software across clients in the USA, Europe, and Australia. I build reliable Playwright test suites, validate APIs end-to-end, and debug complex frontend/backend interactions using browser inspection and network tooling. I believe both automation and manual testing have their place, and I know when to use each. What I enjoy most is the debugging process: tracing exactly where and why something breaks, and building the coverage that prevents it from happening again. 🔹 Core Technical Stack - Test Automation Playwright (E2E, cross-browser, headed & headless) Page Object Model (POM) architecture Test parameterization, fixtures, and parallel execution CI/CD integration (GitHub Actions, pipelines) - API Testing REST API validation with Postman and Playwright's request context Postman collection building, organization, and documentation Request/response schema validation Edge case and error response coverage - Debugging & Inspection Chrome DevTools & network panel profiling Console error triage and performance waterfall review WebSocket and XHR/fetch payload inspection Intercepting and mocking network requests in Playwright - Database & Data Consistency Testing Validating data consistency between Athena and consumer apps or web dashboards Verifying that backend data surfaces correctly across layers Cross-checking API responses against database records 🧪 Services - Playwright Automation Building test suites from scratch or extending existing coverage E2E flows: login, forms, dashboards, multi-step workflows Cross-browser and cross-device coverage - API Test Coverage Functional API testing against staging and production environments Postman collection building and maintenance Validating status codes, response bodies, headers, and latency - Network & Debugging Profiling Reproducing and documenting hard-to-catch frontend bugs via network traces Identifying failed requests, CORS issues, and payload mismatches Logging and annotating DevTools findings for developer handoff Intercept-based testing to simulate backend states - Manual & Exploratory Testing Structured exploratory testing where automation doesn't reach UX flow evaluation, edge case discovery, and regression checks Usability and layout consistency review 📱 Devices Available for Testing iPhone 11 · Google Pixel 10 Pro · Windows 10 PC ✅ Why Clients Choose Me - Genuinely enjoy debugging -- I dig until I find the root cause, not just the symptom - Balanced approach: automation where it scales, manual where it matters - Strong attention to what's happening under the hood, not just the UI - Fast communication, clean deliverables, and proactive flagging - Experience across SaaS, consumer apps, company workflow tools, subscription, and B2B portals - Comfortable in global async teams (US, Europe, Asia timezones)
