    • Hands-on experience with test automation frameworks such as Playwright, Cypress, Selenium, or PyTest.
    • Strong expertise in API testing, including REST APIs, Postman, and backend validation strategies.
    • Experience testing distributed systems, microservices architectures, and event-driven systems.
    • Solid understanding of data flows, message queues, and asynchronous processing systems.
    • Proficiency in Python and/or JavaScript with strong object-oriented programming fundamentals.
    • Experience validating integrations, data pipelines, and system-level end-to-end workflows.
    • Strong knowledge of SQL and ability to analyze and validate data consistency across systems.
    • Excellent analytical, problem-solving, and communication skills to work effectively across technical and product teams.
