Service
Legacy systems, modern stack, zero drama.
The system nobody dares touch, moved to a modern stack the safe way: understand first, pin the behaviour with tests, then migrate one module at a time while the business keeps running.
What this covers.
Behaviour inventory
Every job, trigger, and side effect written down — often the first real documentation the system has had.
Characterization tests
The current behaviour, quirks included, pinned — so unintended change announces itself instantly.
Module-by-module migration
Each slice live and verified before the next begins. No eighteen-month rewrite, no switch-flip bet.
Data migration, verified
Old data into new schemas with reconciliation checks — the part rewrites always underestimate.
A system your next hire can read
Modern stack, current documentation, no more "don't touch it on a Friday."
How every engagement runs.
The Blueprint

Spec, architecture, and a fixed build quote — yours to take anywhere.
The build
from $3,500 · fixed scope
Live from week one. A working demo every Friday, or that week is free.

The system grows; someone senior answers when it matters.
Sound like your situation?
Questions operators ask.
Why not just rewrite from scratch?
Because the old system is the only complete spec of what the business needs, and heroic rewrites are how legacy projects fail. We mine it before we replace it — sometimes the verdict is "keep the core, replace the edges."
The technology is ancient — can you work with it?
Behaviour is behaviour, whatever the stack. If it stores data and responds to input, it can be characterized, tested, and migrated.
Does the business stop during migration?
No — that's a requirement, not a hope. The system keeps running throughout; each module cutover is small and reversible.
