I lead QA teams through the full software delivery lifecycle, from requirements analysis and test planning to execution, defect management, release support, and production issue investigation. I am experienced in mentoring testers, recruiting QA talent, delegating work, and fostering knowledge sharing across engineering teams.

My technical background includes functional, API, database, regression, performance, load, stress, volume, and soak testing. I build and oversee automation frameworks and use modern CI/CD practices to improve the speed, reliability, and consistency of testing.

I am comfortable managing risks, reporting test status, creating test documentation, and supporting UAT and production releases.

I am passionate about delivering high-quality digital products, standardizing testing processes, and driving continuous improvement. I bring strong leadership, analytical thinking, communication, problem-solving, and people-management skills to QA leadership roles.
