What I'm looking for

I’m looking to grow in QA where I can own end-to-end test execution (SIT/UAT/Regression/API/data), strengthen test automation, and deliver clear reporting and bug insights through tools like JIRA and Postman.

I’m a results-driven Quality Assurance and Application Support Engineer with over 7 years of experience in web and mobile application testing. I build comprehensive test plans, test scenarios, and test cases, then execute full test cycles including Smoke, Sanity, SIT, UAT, Regression, API, and data testing.

I’m highly skilled in managing testing workflows using JIRA, performing API validation with Postman, and automating tests with Katalon Studio. I also execute sophisticated data testing and manipulation using TOAD, SQL Developer, DBeaver, and PL/SQL—turning findings into clear, actionable outcomes for teams.

Across projects at TestIO and multiple Indonesian organizations, I’ve delivered detailed bug reports with precise reproduction steps, generated summary/executive testing reports for stakeholders, and collaborated cross-functionally with DEV/BA/SA/PM to align testing strategies with business objectives. I’m committed to delivering reliable, user-focused software through disciplined QA and continuous improvement.
