QA Lead / SDET · Kuala Lumpur
QA Lead at respond.io. I work on test automation, API and mobile testing, and release quality, and I publish open-source test tooling that runs in CI.
I treat quality as a release decision, not a phase at the end. Checks run on every pull request, contracts are verified before deploys, and a red build blocks the merge.
