The middle of the system

Seattle area, since 2000

A data person who never stopped writing application code. I like the unglamorous middle of a system: records that arrive late, twice, or wrong and have to be made right before anyone notices; competing updates that land at the same moment and need a distributed lock to settle; and the paths where every millisecond counts.
