Business Systems
Turning Ad Hoc Estimates into a Repeatable Process
A collaboratively refined estimate template made project scoping more consistent and faster.
Principle: A useful standard improves through real use rather than pretending to be complete on day one.

Systems
Building Reliability Into Scheduled Systems
WP-Cron failures rarely announce themselves. They quietly stop scheduled imports, stale listings accumulate, and support tickets arrive days later. Reliability often means designing around silent failure.
