As an experienced ISTQB Certified QA & Developer, I major in both automation and manual testing. I write multi-platform (macOS, Windows, Linux) cross-browser (Safari, Chrome, Firefox, IE, Edge) testing frameworks using different languages like Java, Gherkins, C# and JavaScript. This means that using my frameworks, tests can run in parallel (the same time) on all platforms and browsers, saving cost, resources, and manpower. I write all sought of automation tests for Mobile, Web, Database, Shell and API using different libraries.
