We modernise and secure your existing web applications, step by step,
with no big bang and without stopping your business.
The application runs, but every change is frightening. The people who wrote it have left, and the documentation left with them.
Unmaintained versions, ageing dependencies, patches falling behind. A client audit or an incident has put it back on the table.
What used to take two days now takes ten. Technical debt has piled up and is now slowing your business down.
How we work
We start from your reality (the stack, the usage, the debt) and move forward in steps. Your tool stays online while the work happens, and you sign off on each stage before the next one starts.
Application audit, mapping of usage, technical debt and security risks. We know what we are touching before we touch it.
What is urgent, what is important, what can wait. Trade-offs decided together and aligned with your budget.
Version upgrades, targeted refactoring, automated tests, hardening. Your tool stays online while the work happens.
Pragmatic AI integration, living documentation, source code delivered continuously. We keep pace with your business.
The goal is not to rewrite everything. It is to make your application safe, understandable and able to evolve again.
Not a hundred-page report, but a readable map of your stack, your risks and your debt, with the work ranked by urgency and costed. Usable even if you then decide to proceed without us.
