It worked perfectly in development. Every screen, every button, every time. Then it went live, and one specific phone on one specific network crashed on the signup screen. #SoftwareTesting #QA #MobileDevelopment #ProductEngineering #Startups

Someone once asked us to "just make it like this app, but for us." That sentence took forty decisions to actually build, and the client never saw a single one of them. We broke down what actually happens between the idea and the launch, the part nobody puts in the pitch.

Every sprint starts with an estimate. Somewhere along the way that estimate quietly turns into a promise nobody remembers agreeing to. We broke down where that shift happens & why it's the real reason engineers start padding their numbers #startups #teammanagement #engineering

Every engineer has asked for a refactor sprint. Almost none of them got one. There's one specific reason cleanup requests keep losing to feature deadlines, and most engineers never say it out loud. #softwaredevelopment #startups #engineering #codebase
