  • The Best Lesson I Learned Came From Building Too Much

    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

    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…

    The Most Underrated Senior Skill is Speaking “human”

    A teammate pings: “Why did this rerender twice? I didn’t change anything.” You can practically hear the “quick sync” calendar invite warming up. Moments like this are where seniority shows up in a way that doesn’t fit neatly on a promo doc: the ability to explain something simply, without assuming shared context. Not because people…

    Developer Experience Is a Feature, Not a Perk

    On Tuesday at 4:57pm, nobody is thinking about “developer experience.” They’re thinking about why the build is taking seven minutes, why the test suite is red in CI but green locally, and why a brand-new teammate is Slack-searching for “how do I run this thing” like they’re trying to defuse a bomb with vibes. That’s…

  • Performance Starts Before the Profiler

    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…
