What I'm looking for

I am looking for a role that values quality, offers growth opportunities, and fosters collaboration.

As a QA Manual Engineer with over four years of experience, I specialize in testing web and mobile applications, ensuring high-quality software delivery. My strong knowledge of the Software Development Life Cycle (SDLC) and Agile/Scrum methodologies allows me to effectively contribute to cross-functional teams. I am passionate about fostering a quality-driven culture, implementing best testing practices, and mentoring new team members to enhance overall product quality.

During my tenure at CLARK, I took ownership of the bug backlog, leading to a remarkable 40% reduction in bugs within a year. I pioneered Developer-Driven Testing, which cut overall testing time by 50%. My proactive approach to code reviews and the introduction of Definitions of Ready and Done have significantly improved process transparency and test coverage. I believe in empowering teams through mentorship, having successfully guided 10 colleagues to adopt a quality-first mindset.

Before my career in software testing, I founded and managed a translation company, which honed my attention to detail and communication skills. I carry these skills into my QA work, ensuring that I not only meet but exceed expectations in delivering quality software. I am eager to continue growing in my career and contribute to innovative projects that prioritize quality and user experience.
