📱 iOS | Android | Web | SaaS | AI | API
I'm a Manual QA Engineer with 7+ years of hands-on experience testing mobile, web, SaaS, and AI-powered products. I specialize in exploratory testing and finding issues standard test cases often miss—edge cases, broken workflows, inconsistent states, usability problems, and real-world failures.
🚀 PRODUCTS I'VE WORKED ON

I tested a women's health product combining physical testing with a mobile app. Users could use Vivo's testing scale/strip and scan it through the app to receive readings such as pH information. I tested scanning workflows, results, usability, device behavior, and edge cases.

I have also tested QUITTR, covering mobile user journeys, progress/streak functionality, interactive features, subscriptions, UI/UX, and regression scenarios.

I test from both a QA engineer's perspective and a real customer's perspective.
I'm IELTS-certified with strong professional written and spoken English, highly responsive, and comfortable working directly with founders, developers, designers, and product teams.
If you need someone who will explore beyond the happy path, find meaningful bugs before your users do, and provide reports developers can immediately act on — let's talk.
