Runtime & dependency upgrades
Move supported runtimes and dependencies forward while isolating compatibility problems.
Modernize · Perl
Digital Desert
Move Perl systems forward without throwing away what they already know.
Modernization should reduce risk and improve ownership. It should not automatically mean replacing years of proven business behaviour with a blank repository.

The work
Modernization begins by preserving knowledge.
A legacy system often contains years of decisions that were never written down. A rewrite can accidentally delete those decisions along with the old code.
A safer sequence is to reproduce the system, characterize behaviour, stabilize what matters, upgrade the runtime and dependencies, then separate or replace components only where the payoff is clear.
Capabilities
Work worth doing carefully.
The service is shaped around the system and the constraint—not around selling a predetermined stack.
Test scaffolding
Create characterization tests around existing behaviour before structural changes become ambitious.
Add tests to legacy Perl →Architecture seams
Separate request plumbing, domain logic and data access where those boundaries create real leverage.
CGI-to-PSGI assessment
Decide whether persistent application infrastructure earns the migration cost in your environment.
CGI vs PSGI →Deployment improvement
Make environments more repeatable and deployment steps more visible without forcing a platform migration.
Incremental replacement
Replace components when the boundary is understood and the economics are better than continued maintenance.
Legacy rescue →How we work
A path from uncertainty to maintainable software.
Evidence first. Change second. The goal is not novelty; it is confidence.
01 — Understand
Map the system, constraints, users and failure modes before proposing architecture.
02 — Protect
Capture behaviour with tests, backups, reproducible environments and small reversible changes.
03 — Change
Improve the system deliberately, document what changed and leave ownership easier than we found it.
