Top Rated - Manual QA | SaaS, Web/Mobile Apps, Digital Ads |

Hey there! I'm a Manual QA Engineer with YEARS of experience making sure digital products actually work, on real devices, for real users. I don't just hunt bugs. I help teams ship smoother, smarter software by blending critical thinking with clear communication. Whether it's a scrappy startup or a scaling platform, I bring structure to chaos with QA processes that catch issues before your users ever see them: saving you time, frustration, and reputation damage. 🛠 Skills Snapshot 🔍 Testing Types Functional • UI/UX • API • Regression • Smoke • Exploratory Cross-browser & compatibility checks via BrowserStack & LambdaTest ⚙️ Tools I Work With Test Management: Jira • TestRail • Confluence • Trello • Azure DevOps API & Debugging: Postman • Swagger • DevTools Databases: SQL • Soql • PostgreSQL (basic querying) Remote Systems: Azure VMs • AnyDesk Other: Stripe (payments, analytics) • Amplitude • Salesforce 🧪 Here's What I Deliver End-to-end testing for web, mobile, and desktop Bug reports that are crystal clear - with repro steps, media, and context Thorough docs: test cases, checklists, exploratory session reports Real-time QA in live environments and remote setups Fast product ramp-up I get your workflow and fit right in 🤝 Why People Like Working With Me ✔️ Thinks like a developer, tests like a real user ✔️ Communicates clearly no mystery bugs, just honest updates ✔️ Fits in fast-agile sprints, ad-hoc releases, or anything in between ✔️ Obsessive about usability, reliability, and that final user click 🤖 AI-Powered Automation I also build automation solutions using AI tools like Claude and ChatGPT, without relying on traditional coding. Instead of writing custom scripts from scratch, I leverage AI to design, generate, and optimize automated workflows, making it faster and more cost-effective for clients who need practical automation without a full dev team. One of my recent projects involved using Claude to build an automated test suite (Playwright, TypeScript) for an AI-powered travel planning platform - covering key user flows including login and a multi-step AI trip generation wizard, while also surfacing real backend/frontend defects along the way. If you're building something people rely on, let's make sure it works before launch. Need a fresh pair of eyes, or a bug-squashing brain?
