Comprehensive QA for Lumai Platform

I’m looking for a meticulous QA partner to put Lumai—our web-based and Android learning environment—through its paces. Functionality is the top priority: every feature must behave exactly as designed, whether the learner is on the browser or our Android app. You’ll start with the Jira test suite we currently maintain. Many cases are there, but the coverage is uneven. I need you to: • Execute every existing case, logging defects with clear steps, screenshots or screen-captures, and severity. • Flag missing or obsolete scenarios, then expand the suite so core workflows, edge cases, and recent releases are fully represented. • Produce an at-a-glance coverage report that shows what was tested, what was added, and where risk still exists. For tooling you can stay inside Jira/Xray for case management; we monitor builds through GitHub Actions and use BrowserStack for device farms, so feel free to leverage those where useful. Please send a concise proposal that describes how you typically approach gap analysis, what metrics you use to prove improved coverage, and any similar education or SaaS products you have hardened. I value depth over length—show me exactly how you will drive Lumai to a release-worthy state, and let’s get started.
