What I'm looking for

I’m looking for a manual QA role where I can run exploratory and functional testing on real web/mobile products, write clear bug reports, verify fixes, and perform regressions—using DevTools, Postman, and Jira-style workflows.

I’m a Manual QA / Junior QA Engineer with hands-on experience in crowd testing web and mobile services, focusing on bug reporting, retesting, defect verification, and short test reports. In a major IT company’s crowd testing work, I followed internal tasks, checklists, and test scenarios while staying accurate and fast under NDA restrictions.

I’ve done practical exploratory testing of a real iGaming web platform—covering registration, authorization, region/currency selection, deposit flow, bonuses, navigation, localization, and responsive behavior. Using Chrome DevTools and Firefox DevTools (Console/Network, XHR/Fetch, HTTP 400/403, pending/failed requests), I identified critical payment/deposit issues and wrote detailed bug reports with priority, reproduction steps, and browser/screen context.

Currently, I test my own web application after frontend/backend changes, checking user flows, data processing states, API behavior, error handling, and UI issues, then running regression after fixes. I also validate request/response behavior with DevTools/Postman and use basic SQL queries when needed to inspect saved processing statuses, defining expected behavior and acceptance conditions before verification.
