Senior QA Engineer at Product Company, reducing regression cycles by ~20% through full-cycle web and mobile testing.

Serbia

Message

At Product Company (NDA), I handle full-cycle QA for web and mobile interfaces, testing functionality and visual details against Figma layouts. I also investigate unreleased features to identify requirement gaps and design inconsistencies before development is complete.

I designed and maintained 300+ test cases and regression scenarios from scratch, which were adopted as a team standard. By improving QA processes, I reduced regression cycle time by ~20% and bug-reopening rate by ~30%.

At Bank Internal System (NDA), I tested internal web systems and backend processes end-to-end. I validated REST and SOAP APIs and database consistency, and analyzed Kafka logs to find event-pipeline inconsistencies.

Earlier, at iGaming Company (NDA), I delivered a mobile app from scratch in under four months with a critical defect rate below 1% at launch. I also developed and executed 200+ manual and automated UI tests across iOS and Android.
