Two projects expose similar helpers. One has no project references. It is missing from the solution most developers build every day. The obvious reaction is understandable: share the code, add the reference, and bring the lonely project back into the...

Hi dev community! I originally published thishttps://www.linkedin.com/pulse/stop-selling-event-driven-architecture-start-business-stephen-tsoi-p6ztc on my LinkedIn Newsletter, but wanted to share it with the dev community here to get your thought...

Any API endpoint that updates part of a record has to decide what a missing field means, whether the client left it alone or wants it cleared. Most business APIs face that decision constantly, because records like customers, orders, and accounts are ...

When I encounter a system or data design decision I'm unsure about, I endeavor to ask the same thing: where does authority live, and how bounded is it? Where Authority Belongs Authority in a software system is the assignment of decision-making powe...

As an architect, a core part of my job is assessing viability and risk before committing a team to building something. That means understanding the problem deeply, testing critical assumptions early, and knowing when to change course. Sprint-based de...

Let me tell you about Sarah. This is a fictional story. But I bet you’ll recognize it. I’ve seen this pattern play out across different companies, different teams, different tech stacks. The details change. The progression doe...

"It works on my machine." We've all said it. But does your bash script work when the third-party API takes 15 seconds to respond? Does your backend service gracefully handle a sudden spike of 503 errors from a payment provider? Writing a full mock ...

For years I have seen teams wrestle with REST in domain-driven systems. They start with clean REST endpoints then gradually compromise as business operations don't map to resource CRUD. After years or just months, they've abandoned most of what made ...

Every developer has heard “Don’t Repeat Yourself” DRY 1. How much code reuse is too much? 2. Am I over-abstracting? 3. Should this be a helper? A util? A service? A hook? The truth: Bad DRY creates more problems than it solves. Good DRY makes ...

I prefer the clean code that is more often produced by throwing exceptions. With the happy path uncluttered by error handling, the implicit propagation of errors to appropriate orchestration layers, and the clean separation of concerns. It's aestheti...

I've worked with engineers who had senior titles but didn't lead anyone. I've also worked with junior engineers who mentored half the team. The difference wasn't in their resume or their technical depth; it was in how they approached their work, thei...
