I was fixing a real bug in a delivery backend I'm building: a customer's order could get created in Postgres even when something downstream failed, leaving an order with no event history behind it. The fix looked simple. Wrap the whole thing in pris...

Docker Agent lets me describe a team of AI agents, their tools, and their guardrails in one config file that a platform team can review like any other piece of infrastructure. That is the part I like most. It also has a permissions trap that I reprod...

If your mobile app decides which step comes next, your backend is trusting the client. That's where we were at Zeney Pay1. Sign-in, KYC and transfers were multi-step flows, and half of each flow's logic lived in the app. The backend couldn't tell wh...

A file hash only means something if you trust the moment it was recorded. That sounds obvious, but it is the part of integrity checking that people most often skip. Here are the design decisions behind the baseline feature in Laravel Scalpelhttps://g...
