Back to original languageAbout Jon
✅ 5+ years in QA & E2E/API test automation
I help product and engineering teams make their releases reliable through robust, maintainable E2E & API tests integrated into CI/CD pipelines.
My goal: reduce regressions, secure critical user journeys, and provide teams with reliable feedback before each production deployment.
⚡ WHAT I CAN HANDLE
→ Automated E2E Tests
Creation or redesign of Playwright/Cypress suites with TypeScript, focused on critical user journeys.
→ API & Regression Tests
REST/API tests with Postman, Swagger/OpenAPI, or Playwright API, smoke tests, and key flow validation.
→ Stabilization of Existing Suites
Reduction of flaky tests, improvement of test data, refactoring of 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 skill transfer.

✅ WHY ME
