About modernization of legacy systems
A legacy system is any software that carries enough technical debt to impede the evolution of the business: obsolete technology, no one wants to maintain it, any change becomes a risk. Modernizing is not rewriting from scratch — it is planning the transition with a cool head, keeping what works and replacing what stops.
When legacy becomes a problem
When delivering a new feature takes 3x longer than it should; when the current team refuses to open the repository; when the server cost is absurd for the real load; when the system uses a stack that no one else hires. These signs indicate that the legacy has stopped serving the business.
Technical audit before any line of code
We start with a 1 to 3 week audit: we map architecture, dependencies, critical technical debt, performance bottlenecks and security risks. The result is an executive report with a plan of attack prioritized by impact vs effort.

Ask a questionStrangler pattern: non-stop modernization
We apply strangler pattern: new features are born in the modern stack, old modules are replaced one by one. The system works all the time, no painful maintenance window, no big bang.
Rewritten only when it makes sense
Rewriting from scratch is expensive and risky. We only recommend it when the original architecture prevents any decent evolution. When we recommend, we do so with a closed scope, controlled parallelism and audited data migration.
Frequently asked questions
+Do you use legacy PHP/Delphi/VB?
Yes, we take on maintenance to stabilize while we design the migration plan for the modern stack.
+How long does a typical modernization take?
From 3 to 18 months, depending on size. Most of the value appears in the first 3 months, with the system now more stable and new features unlocked.
+What if I don't have documentation?
Normal. Reverse engineering is part of the audit. We reconstruct understanding from code and actual usage.
+How much does the technical audit cost?
It is contracted as a closed scope, with a price defined based on the size of the system. The report is yours even if you do not proceed with the modernization.
+Do you take on the support later?
Yes, on a monthly contract. We also prepare your internal team to take over, with documentation and knowledge transfer.
