Hire the Best QA Engineers
in Ukraine

Before going independent, I spent 12+ years in QA with world-leading companies including 8 years at PAR Technology (a restaurant ERP company) leading a 25-person QA organization. I'm ISTQB Foundation and ISTQB Advanced Test Manager certified, with 7+ years focused specifically on test automation. What I do best: - Playwright test automation. Migrate flaky, slow or legacy test suites from Selenium or Cypress into fast, maintainable E2E coverage (JS/TS). - AI-accelerated with senior-QA-directed automation. AI drafts test cases and converts manual scripts into automated suites fast. - Build k6 (browser and/or protocol-level) load and stress test suites to surface performance bottlenecks before they hit production. - QA audits. A focused, fixed-scope engagement that finds your highest-risk bugs and gaps fast, with a prioritized action plan. - Manual & exploratory testing, API testing (Postman), and test strategy/process consulting reinforced by AI where it speeds things up, never in place of judgment. Tools: Playwright (JS/TS), Selenium (C#), Postman, BrowserStack, k6, plus AI-assisted test generation and triage. Domain experience: e-commerce, restaurant/hospitality tech, blockchain, real estate, finance & banking, CRM/ERP systems. I work directly with you — no account managers, no junior hand-offs, no bloated team markups. Available during US and UK business hours (overlap until ~2pm ET), fluent English (C1). Let's talk about what's slowing your releases, flaky tests, coverage gaps, an unproven QA process and fix it.

✅ READY TO START ASAP 🏆 QA AUTOMATION ENGINEER | 3+ years| PLAYWRIGHT SPECIALIST | DRIVING PRODUCT QUALITY WITH AI TESTING Hi, I’m Lina, a Senior QA Automation Engineer with deep expertise in Playwright. I team up with fast-scaling tech companies across the US and Europe to replace sluggish manual QA processes with highly efficient, automated pipelines. My focus is on removing release bottlenecks so your team can ship faster, scale securely, and deploy to production with zero risk. ✔️ QA Automation Engineering: Re-architecting legacy test suites into lightning-fast, highly resilient CI/CD pipelines leveraging scalable Playwright frameworks and uncompromising quality gates. ✔️ AI-Powered QA Strategies: Integrating AI-driven testing agents within robust Playwright environments to optimize coverage and secure complex, non-linear workflows where standard automation falls short. ✔️ Quality-Driven Mindset: Enforcing a zero-noise testing standard. I wipe out flaky tests using Playwright, guaranteeing absolute build reliability for developers and sustaining elite product quality. As a dedicated QA specialist, my focus is on engineering modern testing ecosystems with Playwright that seamlessly bridge the gap between agile development and flawless end-user experiences. Leveraging my background in test automation, I architect robust, production-ready Playwright frameworks from the ground up. I started my path in tech with a deep interest in software quality. Early in my career, I worked as a manual tester, which taught me the tester's mindset - the ability to find edge cases and understand user pain points. This foundation makes me a better Playwright specialist today: I don't just automate scripts; I automate the most impactful scenarios for QA testing. Over the last 3 years, I have evolved into a proficient QA Automation Engineer, leading QA testing efforts for complex web and mobile platforms with a focus on stable Playwright pipelines. WHAT I HELP WITH: 1️⃣. Web & Mobile Automation Architecture I build test suites from scratch using Playwright, WebDriverIO and Appium, focusing on Page Object Model (POM) for maintainability. As a QA testing specialist, I specialize in: ● Building robust suites from scratch with Playwright, WebDriverIO and Appium. ● Advanced UI automation and QA testing with Playwright (JavaScript/TypeScript). ● Modern, fast, and reliable QA testing with Cypress and Playwright. ● Integration with CI/CD tools like Jenkins, GitHub Actions, and GitLab CI. I work as a qa tester ensuring that both web and mobile interfaces function perfectly. 2️⃣. Technical Stack & Market-Leading Tools As a technical automation engineer, I leverage a modern stack for QA testing that clients look for most: ● Frameworks: Playwright, WebDriverIO, Appium, Mocha, Jasmine. ● API Testing: Postman, Axios, Playwright API testing for robust backend validation. ● Infrastructure & DevOps: Docker, Jenkins, Git, BrowserStack, SauceLabs. ● Mobile Testing: Appium Inspector, Appium Device Farm, Xcode/Android Studio. ● Scripting: Python automation, JavaScript/TypeScript, and SQL for QA testing database verification. This allows me to support developers with clear, actionable Playwright data and maintain high-speed delivery. 3️⃣. Quality Assurance Software Strategy I design the QA testing software lifecycle: ● Defining Playwright testing strategies from the ground up for maximum coverage. ● Identifying which parts of the system require QA testing automation for the best ROI. ● Test Management: Using Jira, Zephyr, or TestRail to track QA testing progress. ● Creating professional Playwright reports with Allure for clear visibility of the product state. 4️⃣. Specialized Testing Experience My experience includes QA testing complex systems, including those built on popular CMS platforms. For instance, I have worked as a WordPress developer in the context of QA testing, which helps me understand the internal architecture of such sites. This technical background and Playwright knowledge allow me to identify potential vulnerabilities and architectural flaws much faster than a standard qa tester. 5️⃣. Analytical Testing & Mentoring Even as an automation engineer, I recognize the value of a solid manual QA testing foundation. I often combine my Playwright work with: ● High-level exploratory QA testing to find "hidden" logic bugs. ● Mobile app testing across various physical devices and emulators. ● Mentoring any manual tester on the team to help them transition to Playwright and QA testing. 6️⃣. Performance & Maintenance ● Playwright suite optimization to reduce execution time. ● Maintaining and updating existing POM structures to match UI changes. ● API QA testing to ensure backend stability WHY CLIENTS TRUST ME: ✔️ 3+ years of focused experience as a QA Automation Engineer in QA testing. ✔️ Expert in Playwright, WebDriverIO, Appium, Selenium, Cypress, and Postman. ✔️ Proven track record in building Playwright frameworks
