What I'm looking for

I’m looking for a senior QA role where I can own QA strategy, expand test automation, manage releases, and strengthen security testing—especially in Agile teams. I want to apply AI-assisted testing ideas to improve quality and efficiency.

I’m a Senior Quality Assurance Engineer focused on delivering high-quality, mission-critical software through strong QA strategy, test automation, and release management. I’ve worked across Agile environments, collaborating with cross-functional teams from requirement analysis through deployment while keeping quality a continuous priority.

I’ve built automated test frameworks for microservices architectures and event-driven systems, strengthening test coverage and significantly reducing regression testing time by 60%. I design testing strategies and quality processes that fit complex product needs, including web-based systems and enterprise software.

Security is built into my approach: I conduct vulnerability testing and security assessments following OWASP guidelines to identify and mitigate risks. I also manage test environments, coordinate deployments, and oversee release schedules while maintaining system stability.

Earlier in my career, I led testing for mobile platforms (iOS, Android, Windows) and researched mobile testing automation using Calabash and Cucumber to streamline workflows. Today, I’m actively exploring AI-assisted testing approaches to enhance quality and efficiency, while mentoring teams and promoting continuous improvement.
