Application Maintenance

Application Maintenance & Support

An application is never truly "finished". It must evolve, stay secure, performant and aligned with your business needs.

Whether you have an existing application to maintain or are looking for a reliable partner after a development, we ensure the sustainability of your digital tools.

Risks of an unmaintained application

  • !
    Security vulnerabilities

    Outdated dependencies = open doors to attacks. 60% of cyberattacks exploit known, unpatched vulnerabilities.

  • !
    Performance degradation

    Without continuous optimization, your application slows down. Load times, server consumption, degraded user experience.

  • !
    Growing technical debt

    Every unfixed bug, every postponed update complicates future interventions and increases costs.

  • !
    Progressive incompatibility

    Browsers, OS, third-party APIs evolve. Without adaptation, your application becomes progressively unusable.

Our maintenance approach

  • ✓
    Proactive, not reactive

    Continuous monitoring, automatic alerts, interventions before problems impact your users.

  • ✓
    Transparent and documented

    Every intervention is tracked, every modification documented. You know exactly what's being done.

  • ✓
    Adapted to your constraints

    Planned maintenance windows, zero-downtime deployments, respect for your business processes.

  • ✓
    Long-term partnership

    We know your application, your context, your challenges. No need to re-explain at each intervention.

We develop custom web applications, SaaS platforms, internal business tools, APIs, automations, and system integrations. Each project is unique, and we adapt our approach to your specific needs.

Timelines depend on project complexity. An MVP can be built in 6 to 10 weeks. A complete business application typically requires 3 to 6 months. We establish a precise schedule during the design phase.
What technologies do you use?
We work with modern web technologies: React, Vue.js, Next.js, Node.js, Python, PostgreSQL, MongoDB, and major cloud services (AWS, Azure, Google Cloud). Technical choices are adapted to each project.
Do you offer support after delivery?
Yes, we offer maintenance contracts that include bug fixes, security updates, performance optimization, and new feature development based on your needs.
How does a project with ZAX work?
