Junior QA Engineer
Oleh Blazhko
I break things on purpose so they don't break by accident. A computer science student building a careful, evidence-driven approach to software quality.
About
I'm currently studying computer science at Lviv Polytechnic National University, and I'm drawn to QA because I care about the gap between what's built and what was promised. I'm learning manual testing and test-case design, automation with browser and end-to-end tools, and API testing.
