Who I am
I work at the intersection of manual and automation testing. I like finding weak points in flows, validating data, checking integrations, and making sure a release is not only “working”, but truly stable.

About
QA with a detective approach
What I focus on
API testing, data validation, end-to-end scenarios, integration flows, logs analysis, and debugging in distributed systems and microservices-based environments.
How I work
I treat every defect like a case: collect evidence, isolate the cause, verify assumptions, and provide a clear result for the team.

Case Files
Real QA investigations
Flaky E2E test investigation
Investigated unstable tests with intermittent failures. Identified async data issues and timing problems between services. Stabilized tests by fixing preconditions and verifying data readiness.
File download issue
Debugged failing file downloads in UI tests. Found mismatch between UI behavior and backend processing. Verified correct behavior via API and improved test reliability.
Integration testing
Tested data flow between distributed systems. Validated correctness of data and UI representation. Ensured stable interaction between services.
