Professional Profile

QA Automation Engineer with 5+ years of experience specializing in end-to-end test automation, API testing, and continuous integration. I design, develop, and maintain robust automation frameworks using Cypress, Playwright, and Selenium to ensure comprehensive test coverage and accelerate release cycles.

I excel at implementing strategic automation solutions that optimize regression testing, integrate seamlessly with CI/CD pipelines (GitHub Actions, Docker, AWS), and leverage AI-Assisted Testing techniques including LLM Testing and Model Context Protocol (MCP) for enhanced validation of AI-powered applications. My approach combines modern testing methodologies with performance optimization and infrastructure as code practices.

I am deeply committed to advancing test automation maturity, exploring cutting-edge testing technologies, and applying ISTQB best practices to establish scalable QA processes. My goal is to build reliable, maintainable automation suites that enable teams to deliver high-quality software with confidence and speed.

Testing Experience

Functional Tests

Verifies that the software correctly performs each of its functions according to the established requirements.

Non-functional Tests

Evaluates aspects such as performance, usability, reliability, and security of the application.

Black Box Testing

Focuses on testing the application's functionality without knowledge of internal code or structure.

White Box Testing

Involves testing internal structures or workings of an application, such as code, branches, and paths.

Test Documentation

Creation and maintenance of test plans, cases, scripts, and reports to ensure traceability and coverage.
