I'm a QA Engineer with 4+ years of experience across different domains (fintech, e-commerce, SaaS, web3, AI, etc.) and platforms (web, mobile and desktop), helping product teams release with confidence rather than crossed fingers. I come in, learn your product properly, and build the kind of testing setup that actually holds up, structured test strategies, solid manual and automation testing, and clear communication with your developers so nothing important slips through.

I test like your users, not like your spec sheet. Real user journeys, real edge cases. 30–40% fewer post-launch bug reports for clients who've made the switch. 2. I catch the bug's automation walks right past. Exploratory testing finds permission gaps, UI breaks, and state bugs. Cutting support ticket volume by up to 35%. 3. Bug reports your devs can act on immediately. Every report includes repro steps, severity, environment, and evidence. ~40% faster resolution, no follow-up pings needed. 4. Automation built to last, not to hand off as a problem. Modular, documented regression suites with a flaky test rate under 2%. Your team can own and extend them without me. 5. You'll always know exactly where your product stands. Structured test summaries at every milestone, pass/fail rates, risk areas, and coverage gaps. No surprises at launch.
