Custom Software Development

Custom software begins where off-the-shelf vendors stop: your processes, your rules, your exceptions. LaMeDuSe builds personalised tools that replace the spreadsheet stack with an application that mirrors your business.

The problem you're facing

You have already tried to bend an off-the-shelf product to your processes: useless mandatory fields, rigid workflows, custom developments billed by the vendor and lost at every upgrade. The software ends up costing more than it saves.

Our answer

Custom software reverses the relationship: your rules dictate the application's structure. We model your processes with your teams, then build the tool that runs them : with exactly the fields, controls and reports you need.

What LaMeDuSe takes care of

  • Modelling of your business processes
  • Custom application: interface, business logic, data
  • Migration of your existing data (spreadsheets, legacy tools)
  • Reports and dashboards built around your KPIs
  • Integration with your existing tools (ERP, CRM, accounting)
  • Feature evolution without vendor dependency

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

Unlike a vendor, we have no product to sell you: every piece of software we build is unique, belongs to you, and evolves according to your rules : not our roadmap.

Frequently asked questions

Off-the-shelf works when your processes follow market standards (accounting, payroll). Custom becomes necessary when your differentiation comes from your processes: there, standard software costs you time and money on every single use.

The initial investment is higher, but total cost is often lower: no per-user licences, no permanent adaptation, no dependency on the vendor's roadmap. The calculation runs over 3 to 5 years, not on the initial quote.

Yes, it's a common starting point: we import your spreadsheet history, clean the data and migrate it into the application with integrity checks.

Through planned feature evolution with us under a maintenance contract, or through any other team: the code is documented, tested and yours. No lock-in.
