React Server Components Are Really About Boundary Design
My take: React Server Components are not mainly a rendering feature. They are a boundary design problem. The hard part is not learning what runs on the server versus the client. The hard part is deciding where the line goes so the app stays understandable six months later. That is where teams get in trouble.…

The Best Lesson I Learned Came From Building Too Much
One of the most valuable engineering lessons I learned did not come from getting something right. It came from over-engineering a solution that never needed that much engineering in the first place. At the time, it felt responsible. I built an abstraction that was clean, flexible, and technically sound. On paper, it looked like good…

Code Reviews Should Create Alignment, Not Just Approval
A pull request lands at 4:42 p.m. It technically works. Tests are green. Screenshots look fine. And yet you can feel a trap humming under the floorboards. Not because the code is failing today — but because you can already see what happens next. Another developer opens the file six months from now, tries to…

Developer Experience Is a Feature, Not a Perk

That’s…

Coverage Is a Number. Confidence Is a Strategy.

Performance Starts Before the Profiler
The most satisfying performance wins I’ve ever shipped didn’t come from heroic late-night profiling sessions with fifteen tabs open and a sinking feeling in my stomach. They happened earlier. Quietly. Almost boringly. They happened when someone paused during implementation and asked, “Where does this state actually belong?” Or when we decided to keep a data…
