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.
