Built automation frameworks using Python (Pytest, Selenium), refactoring test flows into reusable modules and increasing critical-path scenario automation from 50% to 80% for 300+ workflows. Translated business requirements into technical specifications, designed executable logic flows, and collaborated closely with backend developers to refine API contracts and ensure system consistency. Performed Linux-based debugging and troubleshooting using tools such as Xshell and VMware; analyzed logs, network traffic, and performance metrics to identify root causes and propose code-level optimizations. Wrote clear and maintainable internal documentation, including system behavior definitions, integration workflows, and user guides, improving cross-team communication efficiency.
