I build QA processes and catch critical web, API, and SaaS bugs before production.
UkraineWhat I'm looking for
At Me Team, I'm the sole QA engineer for a SaaS POS platform, testing booking, menus, and inventory while owning release readiness. I built the QA process from scratch, including workflows, documentation, bug tracking, and REST and GraphQL Postman collections.
I've cut testing time in half through automated tests, increased API test coverage from 50% to 80%, and reduced redundant tests by 30% without losing coverage. I also caught payment failures, booking conflicts, and inventory data-loss issues before production, while early Figma design feedback reduced design-related bugs by about 35%.
Previously at WebUzvar and Baza Trainee Ukraine, I created test cases and checklists, tested REST APIs, reported bugs, and began writing JavaScript test scripts. I'm continuing to explore AI-driven testing through tools including Ollama, ChatGPT, Postman AI, Claude, and testRigor.
