Old systems that still matter, made maintainable again
Every company has one: the system that runs the business, that nobody dares touch, whose original authors have left. It works, mostly. It is also the reason a two-week change takes six months.
We modernize systems like that. Sometimes that means refactoring in place, sometimes a new architecture, sometimes a move to the cloud. It rarely means a rewrite from scratch, and we will say so if that is what you are planning.
Contact usHow we go about it
Read the code before judging it
We audit what is there: what it does, what depends on it, where the risk is. Old systems contain years of business rules that nobody wrote down anywhere else. The audit produces a plan, not a verdict.
Refactor where the code is salvageable
Add tests around the parts that matter, then untangle them piece by piece. The behavior stays the same; the next change becomes possible.
Redesign where it is not
Some structures cannot be refactored into shape. Then we design a new one and move functionality across in stages, with the old system still running until each piece is proven.
Fix the things that do not scale
The single database everything writes to, the nightly batch that now takes all night, the server that cannot get any bigger. These are usually the reason the project started.
Make it fast again
Profile, find the three queries and two loops that take 90% of the time, fix those. Old systems are often much faster than they seem once someone looks.
Move to the cloud, when it makes sense
Lifting a system into the cloud unchanged usually costs more and gains little. We modernize first, then move the parts that benefit.
Hand it over properly
Documentation, tests, a build pipeline and a team that knows the new system. The point of modernization is that the next change does not need us.
What changes afterwards
Changes take days, not quarters
A system with tests and clear structure can be changed with confidence. That is the whole return on the investment.
Cheaper to run
Fewer servers doing the same work, no license for a framework that went out of support in 2015, and fewer 3 a.m. calls.
Easier audits
Supported dependencies, current encryption, and logs that show who did what. Auditors ask about all three.
People are willing to work on it
Engineers avoid the legacy system. After modernization it is just a system, and hiring for it stops being a problem.
We have been the people who left
Most of us have inherited systems like this, and most of us have written code that someone else later inherited. Both experiences make you careful. We modernize with respect for what the old system got right.
