Description

QA Engineer specializing in manual and automated testing, I work on the quality of backend, API, and UI applications. I master Cucumber.js, Selenium, Postman, and writing BDD scenarios. I also have good experience in payment processing (CBAE, CIS, APDU, TLV/LLLVAR) for validating complex flows. I support teams in implementing or improving test frameworks, log analysis, CI/CD integration, and the reliability of critical user journeys. I undertake short, targeted missions with quick deliverables.
