About

Professional summary

I am a Senior QA Automation Engineer with more than 10 years of engineering experience, specializing in end-to-end web UI and API test automation for complex enterprise software.

I currently lead test automation for Schneider Electric Digital Twin platforms. I build scalable Python and Playwright frameworks, validate REST APIs and microservice integrations, and help teams detect defects early in the delivery lifecycle.

I have hands-on experience containerizing automated test suites with Docker and integrating them into CI/CD pipelines. I also perform database verification with SQL and MySQL, supporting reliable data persistence and transaction validation.

My approach combines quality engineering, clean modular test design, Page Object Models, code reviews, and close collaboration with developers in Agile teams. I focus on testability, maintainability, and consistent automated coverage.

Before moving into software quality assurance, I built extensive experience in mechanical design, manufacturing, process engineering, production optimization, validation, and team leadership in the automotive industry.

I bring a broad engineering perspective to QA automation, combining analytical problem solving, process improvement, risk analysis, and practical experience with high-quality enterprise and industrial systems.
