Published a new Contra project:
Payment Lifecycle Integration Backend
This project focuses on a backend problem I care about a lot:
how to keep an internal payment workflow correct when the external provider is asynchronous and outside your control.
The system models:

Just published my third article in the DCDD series.
This one clarifies where DCDD applies — and where it doesn’t.
It’s not about vision or strategy.
It’s about keeping systems buildable when reality is messy.

DCDD Isn’t About Vision — It’s About Making Systems Buildable
DCDD solves how to build, not why to build
Architecture doesn’t fail at code.
It fails before the first line is written.
In many projects I’ve worked on, the real problem wasn’t technology —
It was the lack of a shared structure:
• What is the system actually about?
• What is the core domain?
• What needs to be built now vs...

From Domain Core to Delivery: The Architecture Document Framework I Actually Use
Most architecture documents fail for one simple reason:
From Vague Requirements to Buildable Backend Systems
When requirements are unclear, most teams rush into implementation — and pay the price later.
My approach is to slow down at the beginning and focus on structure before code:
• Identify the true core domain
• Define key entities...

I recently wrote about how I approach complex systems by identifying the true domain core.
This article explains how to move from “busy but unclear” systems to a clear, buildable structure — using a real-world inventory and operations example.
It reflects how I think about system...
