With all my new clients I face the classic situation of "regular test automation" which is rarely fully successful. I can give you some tips on how to find a better approach which I have formulated based on my past experience. Very often automated test cases are a waste of effort due to failed attempts to get added value for the project. All your "regular static scripts/suites" become outdated and irrelevant immediately after the first successful execution. Measurable additional value is achieved only by writing new scripts. Then, you spend more time updating scripts than getting useful information from their execution. In addition, due to the use of some available/popular frameworks, you also face the situation where it is not possible to fully automate test cases due to certain limitations of the chosen framework. So in addition to all these problems, some really important e2e cases still have to be tested manually. All available frameworks are only suitable for creating a simple sequence of a few static actions. True end-to-end testing with a 2-4 hour test runs covering all aspects of the application is impossible. But this is proven to be possible with what I offer, and each such test session is dynamic, unique and adds additional value to the project because of that. You will be able to cover many cornercases and test cases which are currently marked as "not automatable", since instead of static repetitive actions, a set of defined and interconnected requiremnets/expectations is used for creation of user actions sequence. In essence, you get requirements formulated in executable code, which allows you to test your application as close to how a real user will use it as possible. And, there's no AI involved, it's all completely under your control. No dendencies from external random noice generators.

🚀 Transforming QA from a Bottleneck into a Business Advantage As a detail-oriented QA Engineer, I help B2B SaaS, complex fintech platforms, and fast-moving mobile startups accelerate their delivery cycles without ever sacrificing quality. By taking absolute end-to-end ownership of the testing process, I minimize post-release business risks, prevent revenue-impacting bugs, and ensure your software ships quickly as a stable, production-ready product. I understand that in Agile environments, speed is just as important as stability. My goal is to catch critical issues before they reach your customers, protecting your brand reputation and saving development time. 🔍 Comprehensive Quality Assurance: Manual & Automated With over 5,000 hours of Software Testing experience across 30+ platforms, I operate effectively as both a meticulous manual QA Tester and a highly technical QA Automation specialist. I don’t just check if a feature works on the sunny-day paths; I simulate complex user flows, dig into unintuitive areas, and rigorously validate edge cases to ensure your system doesn't break under real-world pressure. Whether I’m stepping in as an exploratory Tester or a strategic Automation Engineer, my approach guarantees a high-quality bar. I bridge the gap between user expectations and technical execution, providing a safety net for your engineering team. My Core Testing Methodologies: 🧪 Functional & Exploratory Testing: Navigating the app like a real user to uncover non-obvious logical errors and UX friction points. 🔄 Thorough Regression Testing: Ensuring that new code merges never break existing, legacy functionality. Every Test phase I run is structured and methodical. ⚙️ API Validation: Going beyond the UI. I inspect network requests, validate JSON responses, and ensure flawless backend-to-frontend data integrity using tools like Postman and Chrome DevTools. 📱 Mobile Device Testing: Validating responsive design, cross-platform UI consistency, network interruptions, and memory scenarios on actual iOS and Android devices. 🛠️ Technical Stack & Frameworks To provide maximum test coverage and efficiency, I build custom solutions and adapt quickly to your existing CI/CD pipelines. UI & E2E Automation: I write robust custom scripts in Python and JavaScript (using Selenium WebDriver, Pytest) and am highly adaptable to modern testing frameworks like Cypress and Playwright. Performance & Load: Using tools like Locust to stress-test your system, identify memory leaks, and verify infrastructure health under high concurrent loads. API Testing: Advanced Postman collections, REST/GraphQL validation, and deep log inspection. Management & Tracking: Mastery of Jira, Confluence, TestRail, and Hiptest for maintaining comprehensive test documentation. 📊 Proven Track Record & Project Ownership I've led QA teams of 4–8 specialists and managed the full quality lifecycle for highly demanding applications, from MVPs to high-load enterprise platforms: ☁️ SaaS & Enterprise B2B: Acted as the lead QA and Automation Tester, building automated pipelines from the ground up. I verified complex business logic, role-based access controls, and data processing for logistics platforms and real estate CRMs. 📈 Fintech & Trading: Handled full-cycle quality assurance for a high-stakes trading platform. I designed and executed complex test scenarios where accuracy and system reliability were non-negotiable. 📱 Native & Cross-Platform Mobile: Executed deep mobile app testing across iOS (Swift/TestFlight) and Android. I handled everything from API integrations and rapid user interactions to validating core posting flows and location-based features. 🏥 Compliance & Healthcare: Performed detailed API and performance testing in a regulated environment where precision and clear documentation are mandatory. 🤝 Seamless Workflow & Clear Communication I'm a strong believer that QA is a communication role as much as a technical one. I don't just wait for instructions — I act proactively. 📝 Actionable Bug Reports: I log defects directly in Jira with absolute clarity. My reports always include expected vs. actual results, severity ratings (Critical, Major, Minor), environment details, and exact, reproducible steps so your dev team doesn't have to guess or ask follow-up questions. 🗣️ Clear Communication: I collaborate closely with developers, product managers, and designers using clear written English to resolve ambiguities early in the sprint. ⚙️ Continuous Integration: I integrate a continuous feedback loop directly into your agile workflow to ensure stable mobile and web releases. If you're looking for a proactive professional who can hit the ground running, take ownership of your quality standards, and deliver bulletproof results, I'm ready to join your team. Let's connect and build something exceptional together!

I build Playwright test automation frameworks that catch bugs before your users do. My last Playwright automation project reduced regression testing time by 60% – and I've helped teams cut release cycles by 70%. If your QA process is slowing you down, let's fix it. I'm a Senior QA Automation Engineer and SDET with 5+ years of hands-on experience in test automation across SaaS, Fintech, Web3, Travel, E-commerce, and Government sectors. I've built QA automation systems for startups shipping their first release, growing companies drowning in manual testing, and enterprises needing a scalable automation engineer to redesign their testing architecture. What Makes Me Different From Other QA Testers and QA Automation Engineers? Most automation engineers deliver scripts. I deliver systems. At my previous role, I built an entire test automation department from scratch with just two engineers. The result? A 70% reduction in release cycles and the QA testers team actually trusted. That's the standard I bring to every engagement — whether it's a two-week Playwright QA automation sprint or a six-month QA automation transformation. I also contribute to the QA automation community through open-source tools. I created playwright-report-server, a reporting solution used by Playwright QA automation teams to centralize test results. I'm also developing TestGraph — a dependency-aware automated test selection engine that runs only the tests that matter after each code change. These tools reflect how I think about test automation: every test should earn its place in the pipeline. My Core Test Automation Stack My primary toolkit is Playwright with TypeScript — the gold standard for modern end-to-end testing. I build Playwright QA automation frameworks that handle everything from smoke tests to complex multi-step user flows across browsers and devices. I also work extensively with: → Cypress — ideal for component testing and fast feedback loops. If your team needs a Cypress-to-Playwright migration, I handle both sides. → Playwright Python — for teams whose automation engineers work primarily in Python. Same rigor as my TypeScript implementations. → Selenium and WebDriverIO — for legacy projects needing modernization without a full rewrite. → Appium — for mobile app testing across iOS and Android when QA automation extends beyond the browser. → K6, Gatling, Locust — for performance testing and load testing when you need to know how your app behaves under pressure. What I Can Help You With Whether you need a QA tester to validate your MVP or a QA automation engineer to build a production-grade test automation framework, here's how I typically help: → Building a test automation framework from scratch — a Playwright automation architecture tailored to your app, team, and CI/CD setup. No cookie-cutter templates. → End-to-end testing and regression testing — reliable E2E tests using Playwright or Cypress covering critical user journeys. Fast, clear failures, seamless pipeline integration. → API testing — REST API testing with Postman, Playwright API context, or custom frameworks to validate your backend before UI testing begins. → Migrating from manual testing to automated testing — I build a test automation strategy that transitions your QA tester team to scalable automated testing without disrupting releases. → Cypress to Playwright migration — full migration: test conversion, framework redesign, CI/CD updates, and team onboarding. → Performance testing and load testing — K6 or Gatling scenarios simulating real traffic to identify bottlenecks before users find them. → CI/CD integration — test automation wired into GitHub Actions, Jenkins, Docker, AWS, and GCP so tests run on every push and deployment. → Mobile testing — cross-platform mobile app testing using Appium for QA automation beyond web browsers. → Software testing strategy — audit your QA process, identify gaps, and build a test automation roadmap aligned with business goals. Industries: SaaS, Fintech, Web3, Travel tech, E-commerce, Government/Public Sector. From compliance-critical fintech flows to high-traffic e-commerce and Web3 dApps — I adapt my test automation approach to your domain. How I Work I'm not a "deliver scripts and disappear" automation engineer. I integrate with your team — standups, PR reviews, mentoring junior QA testers and QA automation engineers, and making sure the test automation framework I build is something your team maintains long after our engagement. I work as an independent QA automation consultant, but I also lead a 15-engineer team at Resolvery specializing in test automation and performance testing — so I can scale up if your project requires it. If you're looking for a QA automation engineer who combines Playwright expertise with real business understanding — someone who builds test automation that accelerates your releases, not just checks a box — message me about your project. I'd love to hear what you're building
