Triage & stabilization
Identify what is failing now, reduce immediate risk and establish a reproducible path to the problem.
Rescue · Perl
Digital Desert
Rescue your legacy Perl application.
The original developer is gone. The server needs upgrading. A dependency no longer installs. Production still matters. Start by recovering confidence—not by promising a rewrite.
recovery-plan.txt
01 reproduce the environment
02 observe real behaviour
03 stabilize production
04 characterize critical paths
05 repair the smallest useful surface
06 document the terrain
07 modernize where it earns its costThe work
When the only safe plan seems to be “rewrite everything,” stop and map the terrain.
Old systems often look chaotic from the outside because their business rules are encoded in years of accumulated behaviour. That behaviour has value even when the code around it needs work.
Digital Desert starts by recovering an accurate picture of the system. Once production and knowledge are stable, modernization becomes a set of engineering decisions instead of an emergency reaction.
Capabilities
Work worth doing carefully.
The service is shaped around the system and the constraint—not around selling a predetermined stack.
Behaviour mapping
Find the important workflows, hidden dependencies and assumptions that a rewrite would otherwise rediscover the hard way.
Characterization tests
Capture what the system actually does before changing code that nobody fully understands.
Testing inherited Perl →Environment recovery
Reconstruct runtimes, dependency expectations and deployment knowledge so the application can be reasoned about again.
Targeted repair
Fix the brittle boundary without turning an incident into an unplanned multi-year platform replacement.
Ongoing maintenance →Recovery roadmap
Document what should remain, what should change and what should be retired—with reasons.
Modernization options →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.
