Summary There are two common ways to build screens. Imperative code tells the computer exactly what to do, step by step. Declarative code describes what the screen should look like for the current state, and the framework updates it for you. Flutter encourages the declarative way. This post keeps things simple, shows tiny examples, and…

Every decision we make affects the budget, the timeline, and the team. That’s why I lean on data; whether it’s through simple…
Event-driven applications aren’t new, but the patterns and discussion in the context of the cloud are hard to miss these days. It’s hard to argue with the patterns and practices because with events, I can build systems that are more reliable, available, and tolerant of fault and issues that arise both in and out of…
Fellow developers, I just published how to give your AI a conscience in 3 lines of code. Not metaphorically. Literally. The problem: Our AI systems make instant decisions about people’s lives – medical treatments, loan approvals, content moderation – in milliseconds. No hesitation. No reflection.
