Experienced Quality Assurance specialist skilled in manual testing, cross-platform validation, and project implementation.
RomaniaWhat I'm looking for
I am a Quality Assurance specialist with extensive hands-on experience testing complex SaaS products across web, mobile (iOS & Android) and Shopify integrations. I execute thorough end-to-end, regression, exploratory, integration and smoke testing to ensure production stability.
At Melian Labs USA – MyTime, I designed and ran comprehensive test plans and cases for booking systems, POS, memberships, marketing tools, inventory, consumer apps and third-party integrations, contributing to the delivery of 800+ features and maintaining a <2% integration issue rate.
I achieved 98% bug validation accuracy, reduced post-release functional bugs by 25–30% YoY, and created test documentation, release notes and setup guides actively used by QA, product managers, developers and clients. I collaborate closely in Agile teams using tools like Pivotal Tracker, Light Tracker, BrowserStack and LambdaTest.
My background also includes project design and implementation for national and EU-funded programs, transport operations supervision, and training delivery. I bring analytical thinking, attention to detail, ownership and a practical, safety-focused approach to every role.
