    About

    About

    QA Engineer with 5+ years of experience testing web, mobile and API-driven products, with deep hands-on expertise in Type/Playwright automation structured around the Page Object Model. Track record of scaling regression coverage for payment gateway APIs, cutting documentation time by 50% with custom AI agents (n8n, local Ollama), and building a Python-based neural network that unlocked full automation coverage in CAPTCHA-restricted areas — work that sits at the intersection of QA and applied AI engineering. Owns test infrastructure end-to-end: containerized environments (Docker, Portainer), CI/CD pipelines (Jenkins, GitLab, CircleCI), log analysis (Sentry, Kibana), and direct data validation with SQL (DBeaver) and MongoDB. Thrives in fast-paced, ambiguous environments, turning complex business requirements into structured, maintainable test suites rather than ad-hocs.
