Senior QA Engineer - API & Automation Testing (Remote / Contract)

Senior QA Engineer (API * Automation * Performance) | Remote Contract & Part-Time I am a Senior QA Engineer with 5+ years of hands-on experience testing complex software systems across multiple domains — including telecommunications, compliance platforms, e-commerce, and data-driven applications. I specialize in API testing, automated testing (Selenium, WebdriverIO/TypeScript, Python), performance testing (load & stress), backend validation, and quality process improvement. I help teams deliver stable, reliable releases by designing effective test suites, automating regression tests, and validating backend logic and APIs. I’ve worked both in full-time roles and contract environments, and I’m now focused on remote, part-time or long-term contract engagements (10–20 hrs/week). Clients hire me for clear communication, strong problem-solving skills, reliable delivery, and a proactive approach to quality and testing challenges. Let’s discuss how I can help ensure your product meets the highest standards of quality.
