I specialise in maintaining and evolving critical systems, and I offer services suited to the needs of IT directors and CTOs who manage long-standing application estates.
Third-party application maintenance (TMA) hands the maintenance and evolution of an application already in production to a provider.
Securing and evolving your application estate. I take over your critical applications to keep them running over the long term.
A legacy migration moves an old application to a current technology while keeping its functions.
A controlled move from your old foundations to modern technologies, without interrupting the service.
Code takeover means reading, correcting and making reliable code written by an AI or coming from a prototype.
Securing and making reliable AI-generated code or quick prototypes.
Mentoring and code review mean reading a team's code and passing on quality practices.
Support for your teams to build skills in software quality.
A code audit measures the quality, security and maintainability of an application, then makes recommendations.
In-depth analysis of the robustness and maintainability of your critical systems.
Expert positioning backed by more than 10 years of experience in industrial and critical environments (CEA, Sopra Steria).
I offer third-party application maintenance (TMA), migration of legacy systems, takeover of code generated by AI, code audits, and mentoring with code review. I work on critical applications written in Java and C#/.NET, for IT directors (CIOs) and CTOs who need them to keep running in production.
My daily rate is between €500 and €600. It rests on more than 10 years of experience in industrial and critical environments, including the CEA and Sopra Steria. To get a quote, the contact button at the bottom of the pricing section copies my email address.
I am based in Montpellier, in the south of France, and I also work remotely. I have led technical work and trained users in English for teams in the United States, India and Europe, on an application deployed in 30 factories in other countries.
Third-party application maintenance (TMA) means handing the maintenance and evolution of an application already in production to an outside provider. I fix complex bugs and add features. On the OP Mobility project, the rework of the historical code cut the number of incidents by 60%.
I migrated a critical banking management application from Delphi to Java Spring Boot, using hexagonal architecture and a TDD approach. I also offer migration of older Java versions to Spring Boot and refactoring of monolithic code, without interrupting the service for users.
Yes. I review code generated by AI or coming from quick prototypes, fix the immediate technical debt and bring the code up to security and performance standards. A code quality audit, with architecture recommendations, is also part of my services.
