- Present

Led Playwright automation architecture, framework modernization, browser validation, SEO testing, performance validation, and AI-assisted quality engineering initiatives across enterprise web applications.

  • Architected a Playwright TypeScript automation framework from scratch with isolated test project, framework utility, component object, and page object layers, reducing automation maintenance effort by 40% across 4 enterprise web applications.
  • Scaled a reusable Playwright automation architecture supporting 4 web applications sharing common UI components, reducing duplicate automation code by 55% and accelerating new test development across engineering teams.
  • Standardized component-based page object patterns, Playwright fixtures, browser context management, locator strategies, API-assisted UI setup, and cross-browser execution workflows, improving framework consistency and onboarding efficiency for multiple engineering teams.
  • Validated browser cookie behavior, authentication tokens, HttpOnly flags, SameSite policies, session persistence, storage state, and client-server cookie flows across browser, BFF, API, and vendor authentication layers, preventing authentication regressions during platform modernization efforts.
  • Implemented Playwright SEO regression testing validating page content, canonical rules, title tags, meta descriptions, structured data, rendered HTML, internal links, and crawlability signals across 500+ SSR pages, reducing SEO production defects and indexing issues.
  • Established AI-assisted engineering workflows using ChatGPT, Claude, GitHub Copilot, Cursor, and Playwright Codegen to generate Playwright test scenarios, draft page objects, diagnose flaky failures, and refactor framework utilities, reducing automation development effort by 30%.
  • Leveraged Playwright trace viewer, screenshots, videos, retries, parallel execution, storage state, request mocking, and browser context isolation to reduce flaky failures by 45% and improve CI pipeline reliability.
  • Analyzed end-to-end web transaction flows from browser client-side behavior through server-side processing, BFF orchestration, downstream APIs, and vendor integrations, improving risk-based automation coverage for critical business workflows.
  • Established performance validation metrics covering Core Web Vitals, client-side rendering, server response time, BFF latency, vendor response time, and end-to-end transaction timing, improving visibility into application performance trends.
  • Decomposed complex product features into measurable business rules, user journeys, SEO signals, edge cases, and risk areas, increasing automation coverage depth while maintaining sustainable execution times.
  • Led technical design reviews with product, engineering, QA, SEO, and business stakeholders to align automation architecture decisions with business risk, release readiness objectives, and long-term framework maintainability.

Additional Sections

Playwright Framework Architecture Projects
  • Designed Playwright framework architecture with isolated page object, component object, framework utility, and test project layers to improve reuse across multiple applications.
  • Created AI-assisted prompt templates for Playwright page object generation, test case expansion, locator strategy review, flaky failure analysis, framework refactoring, cookie/session validation, and SEO regression testing.
  • Built performance-aware automation workflows measuring client-side, server-side, BFF, and vendor response timing for critical web transactions.

Why This Resume Works

  • Positions the candidate as a Playwright framework architect, not just a test script writer.
  • Uses strong ATS keywords such as Playwright TypeScript, component-based page objects, browser cookie validation, SEO regression testing, Core Web Vitals validation, BFF testing, and AI-assisted test design.
  • Shows deep web application understanding from browser client side through server, BFF, API, vendor, authentication, performance, and SEO layers.
  • Demonstrates senior-level technical communication, stakeholder persuasion, architecture reasoning, scalable automation design, and measurable quality engineering outcomes.

Common Mistakes to Avoid

  • Listing Playwright tests without showing framework architecture or scalable design decisions.
  • Missing page object layer separation, reusable component automation, fixtures, browser context management, and CI/CD execution details.
  • Ignoring browser cookie/session behavior, SEO metadata, canonical rules, BFF/API/vendor dependencies, Core Web Vitals, and performance metrics.
  • Describing AI only as test case generation without showing framework refactoring, page object generation, flaky diagnosis, SEO test generation, locator support, or documentation improvements.
