Code takeover and modernization

Take back control of code developed by another provider

Your existing application has become unmanageable? We take over the code, audit it and modernize it. Technical audit, refactoring, documentation: get out of the deadlock and evolve your product with confidence.

Take back control of your application

Your application was developed by a provider who is no longer available? The code has become difficult to maintain, bugs are piling up, and evolutions are increasingly costly? You are not alone in this situation.

We have been taking over existing applications for years. Our team audits the code, identifies risks and proposes a clear action plan. No vague promises: concrete recommendations with precise estimates.

The goal: stabilize your application, reduce technical debt and allow you to evolve it serenely. We document everything, set up automated tests and train your teams if necessary.

Our approach.

A methodical and transparent takeover.

We analyze the source code, architecture, dependencies, security vulnerabilities and technical debt. You receive a detailed report with prioritized and costed recommendations.

We fix critical bugs, update security dependencies and set up a clean development environment. The application continues to run during this phase.

We document the architecture, business processes and APIs. We add automated tests to secure future evolutions and detect regressions.

Benefits.

The advantages of a successful code takeover.

A well-managed code takeover transforms a problematic application into a reliable and scalable tool. You regain control of your application assets.

No more astronomical quotes for the slightest modification, bugs that keep reappearing, impossible updates. Your application becomes an asset again, not a liability.

And if you want to internalize maintenance, we train your teams and transfer all the necessary knowledge to them.

What our clients gain from a code takeover:

Faster and less costly evolutions thanks to clean code

Independence regained from the previous provider

Reduced technical debt and modernized architecture

Internal teams trained and autonomous on the code
