QA is not clicking buttons: it is the quality gatekeeper for the whole SDLC

The article argues that senior QA should act as an end-to-end quality gatekeeper across the full SDLC, not just a manual tester.

It lays out six checkpoints for QA involvement: requirements, design, implementation, pre-merge testing, deployment readiness, and production monitoring.

The piece also highlights a reproducible QA automation workflow using Jira, SQLite, HTML reports, and Slack digests as an example of pipeline-based quality work.

Its core message is that many defects are introduced early in requirements, design, or release processes, so stronger QA improves reliability, observability, and release safety.
