QA Lead / Engineer · 14+ years · Product Builder
강홍재 / James
Fourteen-plus years as a QA engineer, up close with product failure modes, user problems, and release risk. I started by finding defects; today I catch what could go wrong at design time and build the product with that same eye. Open to QA Lead/Engineer roles, and the people and teams I can build alongside.

Positioning
Up close with product risk for 14+ years.
Risk sense
The release-meeting seat where "is this safe to ship?" comes up most often. What could go wrong belongs in the feature design, not the post-mortem.
User problem
Tracker tickets are only a slice of user pain. The frustrations users never bother to file are the ones that should move the product backlog.
Release judgement
GO / HOLD starts with data and ends with a person. The score, the reasoning, and the dissent should live on one screen so the decision holds up later.
Validation loop
Testing isn't a pre-release ritual; it's a loop that narrows a hypothesis. The reproducible-experiment instinct a QA engineer has carries into product discovery.
QA Leadership
Built and led the QA org, 0→1.
0→1 QA team · release gates
