🔍 Most QA engineers find bugs. I find the ones that cost you money. With 5+ years testing web, mobile, and desktop applications across Fintech, E-Commerce, SaaS, and Healthcare, I specialize in two things: making sure your app works — and making sure it holds up when real users hit it at scale. ⚙️ I combine rigorous manual testing with performance testing (JMeter, k6) to catch what unit tests miss: the race conditions, load-breaking bottlenecks, and edge cases that only appear in production. My clients don't find out about critical bugs from their customers — they find out from me, first. ✅ Functional & regression testing across web, mobile (iOS/Android), and desktop 🚀 Performance & load testing to validate your app survives real-world traffic 🛡️ Industry-specific risk awareness: compliance, data integrity, payment flows 📋 Clear bug reports with reproduction steps, severity tagging, and fix suggestions 💼 Experience in Fintech, E-Commerce, SaaS, and Healthcare — I know the high-stakes scenarios ⚠️ If your product handles transactions, patient data, or high-traffic commerce — a crash isn't just an inconvenience. It's a crisis. Let's make sure it never gets there. 📩 Open to hourly engagements, project-based testing sprints, and ongoing QA retainers. Message me with your tech stack and I'll tell you exactly how I'd approach it.
