Web Application Development

A web application is accessible everywhere, updated instantly, and requires no installation. LaMeDuSe builds custom web applications : from internal tools to multi-tenant platforms.

The problem you're facing

Your legacy client-server applications force your teams through VPNs, updates go through individual installations, and a crashed workstation takes the work with it. Meanwhile, your competitors ship updates with a single click.

Our answer

We build modern web applications: fast, responsive interfaces, secure APIs, continuous deployment. Your teams access them from any browser, updates are immediate for everyone, and the application scales as your business grows.

What LaMeDuSe takes care of

  • Responsive web application (desktop, tablet, mobile)
  • Secure API with authentication and role management
  • Admin interface tailored to your processes
  • Automated testing and continuous integration
  • Deployment on your infrastructure or ours
  • Monitoring, backups and maintenance

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.

Relevant technologies

React & Next.jsNode.js, Go, PythonPostgreSQL, RedisKubernetes & DockerCI/CD GitHub Actions

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 develop and operate our own web platforms on our European infrastructure: the technical choices we make for your applications are the ones we rely on for our own.

Frequently asked questions

React and Next.js for interfaces, Node.js, Go or Python for APIs, PostgreSQL for data. Standard, widely documented technologies that don't lock you in with one vendor.

Partially, yes: PWA technologies allow degraded offline operation with resynchronisation when the network returns. For a fully offline need, a desktop application is sometimes better : we'll tell you honestly.

On our European infrastructure (France, Germany, Switzerland) with monitoring and backups, or on yours if you have specific constraints. In both cases, deployment is automated.

The architecture is sized to your actual and projected volumes: from a few dozen internal users to tens of thousands of simultaneous visitors. Load testing validates the sizing before go-live.
