When to stop testing and ship

Posted on March 2, 2022 By Luis Fernandez

Story led opening At 1 a.m. the Slack pings were still coming in. A junior QA found a flicker on the checkout button if the network tab was throttled to slow 3G. The fix was a one line change. The sprint was already stretched. We had a paid campaign scheduled…

How to avoid over personalizing

Posted on September 14, 2021October 21, 2025 By Luis Fernandez
