Hi, I’m Deyan Naydenov, a QA Automation Engineer with 3 years of hands-on experience in Agile teams. I design and scale end-to-end testing frameworks using Playwright and TestCafe, integrating them into CI/CD pipelines on Azure DevOps. I’ve reduced manual regression cycles, stabilized flaky tests, and expanded test coverage while collaborating with developers and product teams to define acceptance criteria and quality metrics. I also streamline test environments (vSphere, Singularity) and create reusable utilities, while growing my focus on performance testing and API validation. I enjoy sharing QA knowledge, writing internal documentation, and helping cross-functional teams ship reliable software.…Hi, I’m Deyan Naydenov, a QA Automation Engineer with 3 years of hands-on experience in Agile teams.
