What I'm looking for

I seek roles where I can build scalable, low-maintenance automation, apply LLMs to testing, mentor teams, and increase automated coverage in delivery-focused environments.

I am a Test Automation Engineer with hands-on experience designing modular frameworks and maintaining automation across web, mobile, and backend systems. I prototype LLM-based workflows for test case validation, synthetic data generation, and code recommendation to improve automation efficiency and reduce maintenance.

My work history includes progressive QA automation roles at Newtech where I developed and maintained frameworks using Playwright, Selenium WebDriver, JavaScript, Java, C#, and supporting tools like Jenkins, Jira, Postman, and SQL Server. I have led automation efforts for banking, networking, and smartphone projects, increasing automated coverage and accelerating bug detection.

I bring strong documentation, defect monitoring, and data-querying skills, and I enjoy mentoring new team members and improving processes. I am self-motivated, detail-oriented, and focused on delivering maintainable, high-coverage test suites that align with delivery requirements.
