We design new systems for the constraints they will actually face, and we untangle the ones that drifted from the diagram a decade ago.
Every important decision becomes a written record. The team after us should not have to guess why.
We design around the problem the team will hit in eighteen months, because that's when the architecture either pays off or doesn't.
Most systems we rescue don't need a rewrite. They need three honest weeks of refactoring and a clear seam.
An incoming founding engineer or CTO wants a second set of eyes on the system before they commit. We deliver a written review in two weeks.
A system that works but slows the team. We produce a sequenced plan that lets work continue while the substrate shifts.
A new module that has to coexist with the rest. We design the seam, name the events, and write the first version.
