Application Maintenance

Living software evolves: bugs to fix, dependencies to update, business needs that change. LaMeDuSe takes over application maintenance : whether we built the app or not.

The problem you're facing

Your application runs, but nobody really maintains it anymore: the agency that built it moved on, documentation is stale, and every upgrade is a leap in the dark. Debt piles up until the day a security patch becomes urgent.

Our answer

We take your application back in hand: code and setup audit, stabilisation, documentation, then maintenance on a fixed-fee or per-ticket basis. Fixes, upgrades, evolution and user support : with a team that becomes expert in your product.

What LaMeDuSe takes care of

  • Takeover audit: code, infrastructure, technical debt
  • Stabilisation and catch-up plan
  • Corrective maintenance: bugs, security patches
  • Evolutionary maintenance: small and medium changes
  • Dependency and platform upgrades
  • Level 2 and 3 user support
  • Monthly reporting: incidents, changes, application health

Our methodology

  1. 1

    Product discovery

    Workshops with your business teams to turn the need into scope, user journeys and measurable success criteria.

  2. 2

    Design & architecture

    Wireframes, technical architecture and documented stack choices: every decision is argued and reversible.

  3. 3

    Iterative development

    Regular releases to staging environments, systematic code reviews and demos at every iteration.

  4. 4

    Production & operations

    Automated deployment, monitoring, bug fixes and continuous improvements with the same team.

Security

Systematic code review, secrets management, monitored dependencies and security testing built into the development cycle : security is a starting requirement, not an option.

Hosting & infrastructure

We host your applications on our own European infrastructure (France, Germany, Switzerland): development and operations are carried by the same group, with no dependency on US cloud.

Maintenance

Application maintenance contracts covering bug fixes, upgrades, feature evolution and user support : the team that designed the software is the team that keeps it alive.

Why LaMeDuSe

We maintain the applications we build : and take over others. Our ability to host and monitor the application alongside its maintenance makes the difference: when an incident is ambiguous, the same team looks at the code AND the infrastructure.

Frequently asked questions

Yes, after a takeover audit: we assess the code, documentation and infrastructure, then present an honest assessment with a takeover plan : sometimes starting with stabilisation before evolution.

Corrective maintenance (bugs, security), adaptive maintenance (upgrades, compatibility), evolutionary maintenance (small changes) and user support. The exact scope is defined by contract, fixed-fee or per-ticket.

By severity: critical within hours, major within 48 hours, minor scheduled. Response-time commitments are part of the contract, and monitoring often alerts us before you notice the problem.

It can: application maintenance and hosting on our European infrastructure form a coherent whole : one point of contact for code and infrastructure. But each service remains separately contractable.
