Introduction
Senior QA Engineer with over ten years of experience driving software quality across complex digital products, embedded systems, mobility solutions and enterprise applications. I specialise in functional testing, test strategy design, Agile delivery and end-to-end defect management, ensuring stable, reliable and user-centred releases. I have led QA activities across major environments including mobility ticketing systems, e-commerce platforms, construction management tools and multi-brand automotive websites. My expertise covers requirements analysis, test design, regression campaigns, workflow monitoring, API testing and structured documentation. I work closely with Developers, Product Owners, Scrum Masters and cross-functional teams to improve delivery velocity, strengthen quality gates and enhance testing efficiency. Proficient with Jira, Azure DevOps, Xray, HP QC, TestRail, Selenium, Postman, SoapUI, SQL, AWS and Confluence, I bring a strong capacity for troubleshooting, reporting, stakeholder communication and process optimisation. I also have significant experience onboarding QA analysts, coordinating offshore teams and supporting functional acceptance phases. Certified ISTQB Foundation, Professional Scrum Master I (PSM I), Professional Scrum Product Owner I (PSPO I) and BULATS, I combine technical expertise, Agile practices and strong communication skills to support international, fast-paced and quality-driven projects. Open to senior QA roles, new challenges and meaningful collaborations. Contact: [email protected]
