Hi, I’m Axel Saballos, a seasoned QA Engineer with a proven track record of designing and implementing robust quality assurance strategies tailored to fast-growing organizations. I specialize in developing robust QA solutions both manual and automated and have successfully built custom automation frameworks from the ground up using tools like Playwright, WebdriverIO, and Selenium. My approach is not just technical it's strategic. I create test architectures that are scalable, maintainable, and traceable from business requirements to test results. Tools like Jira and Zephyr allow me to ensure end-to-end traceability, linking user stories and acceptance criteria to test cases, execution cycles, defects, and metrics. This not only enhances visibility for stakeholders but also aligns QA efforts directly with business value and compliance standards. Additionally, I work with technologies like MySQL to validate data integrity during testing, ensuring a full-spectrum QA approach across layers of the application. More than just executing tests, I focus on building QA teams, processes, and cultures from the ground up, establishing a clear roadmap for quality across the organization. If you're looking for someone who can lead QA strategy, implement tailored testing frameworks, and deliver full traceability throughout your development lifecycle, I’d be thrilled to contribute my experience to your team.

🚀 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 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.
