Custom Software Development

Custom software fits your processes instead of imposing its own. LaMeDuSe designs, builds, deploys and maintains business software for companies that have outgrown generic tools.

The problem you're facing

Your business has processes that exist in no off-the-shelf product. You stack spreadsheets, re-enter the same data twice, and every new requirement becomes another workaround. Generic tools make your company adapt to the software : the opposite of what a tool should do.

Our answer

We start from your real processes, observed with your teams, and build software that covers them exactly: no more, no less. The result is a tool your teams actually adopt because it mirrors how they work : built by a team that can also host and maintain it.

What LaMeDuSe takes care of

  • Documented functional and technical scoping
  • Application architecture and data model
  • Developed, tested and deployed application
  • Staging and production environments
  • Functional and technical documentation
  • User training and knowledge transfer
  • Corrective and evolutionary 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

LaMeDuSe is not just a development agency: the group operates its own European infrastructure and hosts the software it builds. The team that designs your application can deploy, monitor and evolve it : with no third-party dependency.

Frequently asked questions

Cost depends on scope: a focused business application typically starts in the low tens of thousands of euros, a full platform costs more. We produce a priced scoping after a few workshops, with phase-by-phase commitments to keep the budget under control.

A first useful deliverable usually ships in 2 to 4 months. We deliver in iterations: you see the software progress from the first weeks, and priorities adjust along the way instead of being frozen upfront.

The code is yours from the first payment, and every phase ends in a deliverable, documented state. You can take over with another team at any time : we work with standard technologies, no proprietary lock-in.

No. We deliver software that runs anywhere: your cloud, your servers or ours. But hosting with LaMeDuSe has one advantage: the same team develops and operates, which removes the ping-pong between a vendor and a host when an incident happens.

Systematic code review on every merge, automated tests on critical paths, continuous integration and dependency auditing. Code is written to be read and maintained, not just to work.
