Dear To whom it may concern,

I am excited to apply for the Junior Applications Tester role at Grab. As a detail-oriented graduate with hands-on experience in automated testing frameworks and Agile methodologies, I am eager to contribute to Grab's mission of building reliable technology that connects people in Southeast Asia. My academic project in software testing for a mobile food delivery app at Nanyang Technological University (NTU) has prepared me to identify critical edge cases and ensure seamless user experiences—values I deeply admire in your innovative platform.

During my internship at Starhub, I collaborated with developers to implement automated test scripts using Selenium and Katalon Studio, reducing bug resolution time by 30% for their customer portal. At DBS Bank's fintech division, I conducted smoke tests for a mobile banking application, achieving 98% test coverage and identifying 45+ critical defects before UAT. These experiences honed my ability to work in fast-paced environments while maintaining precision—a skill I believe is essential for ensuring the quality of Grab's expanding suite of mobility services.

Grab's commitment to redefining urban mobility through technology resonates with my passion for creating robust digital solutions. Having used Grab's ride-hailing and food delivery apps daily, I understand the importance of rigorous quality assurance in maintaining user trust. I am particularly interested in contributing to your efforts in expanding AI-driven features, where my training in test automation and analytical mindset could directly support the team's goals.

I would welcome the opportunity to discuss how my technical skills and enthusiasm for quality assurance align with Grab's vision. Thank you for considering my application—I look forward to potentially contributing to your team's next great innovations.
