Reduced production defect leakage from 5.53% to 2% by leading 10 QA engineers across five product squads and establishing shift-left validation, release gates, and risk-based quality governance. Cut critical regression execution from approximately two hours to 30 minutes by designing the company's first Playwright-BDD/TypeScript automation MVP.

Delivered validation of all 1,638 migration scenarios, including 1,635 automated passes and only three manual checks, by leading automation and release readiness for business-critical platforms. Maintained more than 90% automation coverage across critical business flows by setting regression priorities and improving API/UI automation architecture.

Improved effective test coverage by 97.2% and QA productivity by 300% by establishing organization-wide quality governance, risk-based testing, and shared engineering ownership. Reduced regression execution from two days to 80 minutes by directing the redesign of more than 1,000 test cases into 28 risk-prioritized critical business flows.

Increased project delivery success from 30% to 90% within six months by improving portfolio planning, dependency management, execution discipline, and stakeholder alignment. Reduced customer-support resolution time from approximately 3 hours 24 minutes to 27 minutes and operational completion time from more than 30 days to 7–14 days by leading cross-functional platform modernization.

Scaled the Quality Engineering organization from 8 to 24 engineers by establishing team structures, hiring and development practices, automation strategy, and shared quality standards. Reduced regression testing from 10 days to three days by defining the automation roadmap and scaling web, mobile, and API quality capabilities across product teams.

Improved release confidence across five payment areas—payment gateway, QRIS, EDC, SDK, and financial transactions—by designing and maintaining automated API and UI testing frameworks. Reduced regression and integration risk by embedding automated functional checks into CI/CD pipelines for mission-critical payment-processing services.

Improved release confidence for products serving millions of users and merchants by leading quality engineering across mobile, marketplace, and platform services. Accelerated web and mobile regression validation by building Selenium and Appium automation frameworks and integrating them into CI/CD workflows.

Reduced repetitive regression effort by developing reusable UI automation and functional coverage for critical enterprise CRM workflows. Improved delivery confidence across implementation and presales engagements by validating customer workflows and communicating product risks to technical and business stakeholders.
