Led end-to-end automation strategy using Robot Framework and Python, achieving a maintainable, scalable test suite covering complex frontend workflows. Integrated automated test suites into CI/CD pipelines (GitHub Actions / Jenkins), enabling continuous quality gates on every pull request and reducing regression cycle time. Authored comprehensive test plans, risk matrices, and coverage reports aligned with business requirements and sprint goals. Owned full integration testing across UI and API layers — using Postman for REST API validation and MySQL queries to verify data integrity. Mentored junior QA engineers in automation best practices, structured bug reporting, and shifting testing left in the SDLC. Partnered with UI/UX designers, product managers, and developers to define acceptance criteria and executable test strategies. Maintained tooling currency by adopting new Selenium and Robot Framework releases; introduced BDD practices to align dev and QA teams.

Built custom web crawlers and UI automation workflows using JavaScript, Jest, and Puppeteer to automate data extraction and regression validation. Designed and implemented Jest-based automated test suites ensuring correctness, reliability, and performance of web crawler code. Engineered error-handling mechanisms for dynamic web elements and unexpected UI states, reducing flaky test failures. Ensured all automated frontend interactions respected website terms of service and internal security compliance standards.

Authored detailed manual test cases from software requirements, ensuring full UI and feature coverage across multiple release cycles. Executed structured manual test suites, identified frontend defects, and delivered concise, actionable bug reports. Communicated testing progress, quality metrics, and release readiness to support smooth delivery cycles.
