Dear Hiring Team, I’m excited to apply for the Senior QA Engineer position. I bring over 10 years of experience ensuring quality across Web, API, and data-driven platforms, with a balanced background in both deep manual testing and modern automation using Playwright (JS/TS). In my most recent role at Crown Castle, I owned the full QA lifecycle for a large analytics platform—writing 600+ test cases, validating UI/API/data flows, and partnering closely with developers and the product owner to block low-quality stories early. I also designed the initial Playwright automation structure and proof-of-concept tests, reducing repetitive manual work and laying the foundation for future automation scale-up. Before that, at Qwiet (ShiftLeft), I supported a cybersecurity SaaS product through functional, API, and regression testing, while helping stabilize the Selenium-Python automation suite and monitoring CI runs. These combined experiences strengthened my ability to identify edge cases early, ensure data accuracy, and support reliable deployments in Agile environments. I’m confident I can bring strong testing judgment, dependable execution, and thoughtful automation growth to your team. I care deeply about product quality, clear communication, and being a reliable partner for engineering. Thank you for your time and consideration. I would welcome the opportunity to contribute to your team.
