Freelancer profile translated to English.

Description

I help product and engineering teams make their releases more reliable through robust, maintainable E2E and API tests integrated into CI/CD pipelines.

My goal: reduce regressions, secure critical user journeys, and give teams reliable feedback before each production deployment.

⚡ WHAT I CAN DO

→ Automated E2E Tests

Creation or refactoring of Playwright/Cypress suites with TypeScript, focused on critical user journeys.

→ API and Regression Tests

REST/API tests with Postman, Swagger/OpenAPI or Playwright API, smoke tests, and key flow validation.

→ Stabilizing Existing Suites

Reducing flaky tests, improving test data, refactoring unstable scenarios, and more readable reporting.

→ CI/CD Integration

Connecting tests in GitLab CI, GitHub Actions, Jenkins, or Azure DevOps with actionable feedback on PRs.

→ QA Strategy

Coverage audit, risk-based prioritization, quality gates, documentation, and knowledge transfer.
