What I'm looking for

A remote QA Automation / QA Engineer role, full-time or contract, on a product team that values quality. I want to own test strategy and automation for web and mobile, and to use CI/CD and AI tools to ship faster with confidence.

I'm a QA Engineer with 3+ years of experience in test automation, working in Agile/Scrum teams from requirements through release.

At Nimbus Tech I test web and mobile (iOS and Android) applications end to end. I build automated suites in Playwright and Appium, run them in GitHub Actions CI/CD, and do manual and exploratory testing. I also validate APIs in Postman, check data with SQL queries and trace issues through logs and AWS. I connect my tools (GitHub, Jira, Linear, QA Sphere, cloud) to Claude, which lets me plan tests, write automation and analyse failures faster.

I also freelance with PropWise, testing a real estate web application. My work there covers test cases, regression, exploratory and cross-browser testing, API testing and Playwright automation (JavaScript/TypeScript).

Before that I worked as a QA Tester at Incisive QA. Earlier I held management roles in hospitality.
