I help indie founders and small teams catch critical bugs before their users do.

I specialize in pre-launch QA audits for web apps and APIs — testing the user flows, edge cases, and backend behavior that developers are too close to their own product to spot.

Trained through TripleTen's QA Engineering program, where I completed 6 end-to-end testing projects across web, mobile, and API environment
