Mainframe modernization

Mainframes paid for themselves. Modernize the parts that need to move, leave the parts that don't, and stop pretending it's all-or-nothing.

Mainframe modernization
What we actually do

The work, on one page.

Estate assessment

What runs, what matters, and what genuinely needs to move — with the dependency map to prove it.

Patterns library

Re-platform, re-host, re-architect, retire — the right pattern for each workload, with the cost case behind it.

Coexistence

APIs, events, and contract testing that let modern services talk to the mainframe safely while you migrate.

Receipts, not narratives

Recent work.

Insurance

Quietly modernized.

Migrated the customer-facing experience off the mainframe without taking the policy engine down.

Common questions

The honest version.

Do you ever recommend leaving it on?+

Often. The mainframe is a perfectly good database in some shapes — the question is the experience around it.
