01The need
A critical system still holds up but is becoming risky: obsolete technology, no one knows the code anymore, every change takes weeks. You want to modernize it without disrupting operations or rewriting blindly. We stabilize it first, then transform it.
02What we take on
- Audit of the existing system and debt mapping
- Progressive migration strategy
- Refactoring and restoring test coverage
- Updating frameworks and dependencies
- Rebuilding documentation and knowledge
- Security hardening and performance improvement
03How we work
No big bang: we move forward in reversible increments, with tests that catch any regression. You keep a working system in production at every step. We document along the way so your team can take back control.
04How we work with you
We start with a short audit, usually 3 to 5 days. We read the code, talk to the people who maintain it, and map the debt: what is fragile, what is no longer tested, what is blocking your changes. You come out with a costed, prioritized action plan, not a report that gathers dust.
Then we transform in reversible increments. Before touching a sensitive area, we put it back under tests: each step ships with a regression safety net and can be rolled back if needed. The system stays in production throughout, with regular demos so you can follow progress. We start with the workstreams that cut risk the most, and we adjust as we go depending on your context.
05What you get
In the end, the goal is simple: a system your team is no longer afraid to touch. Concretely, you walk away with:
- Cleaner code that is easier to evolve
- Technical debt mapped and reduced by priority
- Test coverage that secures future changes
- Up-to-date frameworks and dependencies, free of known flaws
- Rebuilt documentation and knowledge transfer to your team
06When to call us
There is no magic threshold: if one of these signals rings true, a short audit is often enough to see clearly. We reply within 24 hours, and the first call is free.
- The application is slowing down and every change takes weeks
- Dependencies are obsolete or carry known vulnerabilities
- Your team is afraid to touch it, or you are inheriting a codebase no one knows
