ISTQB-certified QA Engineer with a proven track record in leading and managing QA processes for complex, high-traffic platforms like LiveOps. I bring a strategic approach to quality assurance—focusing on optimizing test coverage, improving team efficiency, and ensuring smooth, on-time releases. I’ve successfully scaled QA teams based on project needs, reducing post-release issues by over 30% and boosting overall product reliability.
My work involves tight collaboration with cross-functional teams, including developers, CRMs, and product owners, to align quality efforts with business goals and user expectations. I’ve introduced process improvements that increased team productivity, enhanced testing consistency, and supported faster onboarding of new team members. I also mentor junior QAs and conduct internal training, including ISTQB exam preparation.
I take full ownership of the QA lifecycle—from requirement analysis and test planning to execution, release validation, and production monitoring. I’m experienced in testing across web, mobile (iOS & Android), and API layers using tools like Postman, Charles Proxy, and MongoDB. I create detailed acceptance criteria, test cases, and documentation that support clear communication and high-quality outcomes.
Passionate about delivering seamless user experiences, I bring technical depth, leadership, and a results-driven mindset to every project—ensuring quality isn’t just checked, but built into the product from the start.More...
