ServicesMODERN
Lower the cost and risk of legacy software without a disruptive big-bang replacement.
We move one workflow at a time, preserve identifiers and history, and retire old components only after the replacement is proven. The operation keeps running while support cost and change risk decline in stages.

How we replace a legacy system
Strangler pattern
One loop at a time behind a facade. No big-bang your plant cannot afford.
Data migration
P-204 stays P-204. History does not become mystery. Identifiers survive.
Interface parity
The operator sees the new screen with the numbers of the old one. Trust survives the cutover.
Coexistence
Old and new run in parallel with a source of truth per record. Not a diff war.
Cutover choreography
Runbook by role and hour. Rollback path defined before the switch, not during.
Decommission
The old system is retired with the audit trail preserved. Nothing quietly still on.
This is what the software we build looks like.
A fragment of SGI Digital — not a photo of the screen. Data is synthetic; the workflow is the one we review with a client.

Custom software
Replace manual coordination and disconnected records with one system built around your process.
AI & intelligent agents
Automate reading, drafting, routing, and follow-up while people retain control of consequential approvals.

Have an operation that generic software can't fit?
Bring the loop that is currently a spreadsheet. We will say whether this is custom software, a product, an agent — or not ours.
