Personal stuff

If a remote discussion needs a call, start with a short written proposal: context, options, recommendation. Meetings go faster when the thinking is already visible.

Before opening a PR for a cross-service change, I draw the request path on a whiteboard (or Excalidraw). Half the bugs die in that sketch.

fun process(order: Order?): Result {
    if (order == null) return Result.Invalid("missing order")
    if (!order.isPaid) return Result.Invalid("unpaid")
    return Result.Ok(fulfill(order))
}

WHERE ...;
