I deliver quality assurance for Worldline, Atos, and Ingenico environments, validating payment processing, fraud detection, transaction flows, and hardware integrations across web and mobile solutions.
With 15+ years across FinTech, telecom, web, and mobile products, I build risk-based test plans, validate banking schemes and data mappings, and investigate issues through SQL, API, JSON, XML, CSV, and Unix checks.
At VivaCell-MTS, I led QA for more than 2,000 products and services spanning calls, SMS, mobile internet, roaming, charging, billing, video streaming, IVR, and USSD through market launch.
I also bring hands-on Flutter/Dart, Android, Python, Playwright, and pytest experience, plus a foundation in web development and systems engineering. I work closely with engineering, business analysis, DevOps, product, and project teams to turn complex delivery dependencies into release-ready products.
