We solve the technical challenges of Shiny applications, from design to production.
Free intro call, no commitment.
If you're here, it's because your Shiny application is facing one of these problems.

Stability
Bugs, calculation errors, or an unstable application undermine the trust of your teams and your clients.

Performance
A slow application hinders adoption and degrades the user experience.

Autonomy
Code that's hard to maintain, poorly documented, or dependent on a single person creates a major risk for your organization.

Profitability
A poorly scoped project that evolves without a clear vision ends up costing more than it delivers.
Case Studies
Cartoline Project
Complete redesign of a multi-screen application with integration of a graphic mockup.
The Cartoline tool is a predictive maintenance information system used by Enedis to anticipate incidents.


DebtwatchR Project
UX/UI improvement on a tool designed for the general public.
In collaboration with the OFCE (French Economic Observatory).


ERC Lynx Tool
Server deployment to host an R Shiny application with authentication and extensive simulation calculations (10+ hours per scenario).
The ERC Lynx tool aims to Avoid, Reduce and Compensate Lynx mortality caused by collisions with transport vehicles.

Our team supports you in growing your applications from a simple "it works" to performant, truly operational tools.
Audit
Identify precisely what's weakening your application.
Is your application slow? Unstable? Hard to evolve?
We perform a comprehensive audit of your Shiny application:
code, architecture, performance, security, infrastructure.
The goal is not to produce a theoretical report but to give you a clear picture:
- actual risks,
- action priorities,
- high-impact optimizations.
You know exactly where you stand and how to secure your roadmap.
Custom Development
Build a reliable, performant, and long-lasting application.
We design and develop Shiny applications tailored to your business challenges.
Every project is structured from the start to ensure:
- a solid architecture,
- controlled performance,
- a smooth user experience,
- maintainable and scalable code.
We don't build a prototype. We build your strategic tool, designed to grow within your organization.
Hosting
Secure, stable, and fully managed hosting.
A performant application is not enough. It also needs to be properly deployed.
We design and manage hosting environments tailored to your needs:
- data security,
- access management,
- performance under load,
- supervision and monitoring.
Your application is available, stable, and secure. No more stress at deployment time.
Ongoing Maintenance
A Shiny application is never set in stone: evolve your application without creating technical debt.
New features, optimization, partial redesign, UX improvements: we handle the necessary evolutions while preserving the stability and performance of the existing system.
Every evolution is designed to:
- maintain reliability,
- avoid accumulating complexity,
- ensure the durability of your tool.
Your application gains maturity with every evolution.
Mentoring
Accelerate your projects while strengthening your autonomy.
We work alongside you to structure, challenge, and secure the development of your Shiny applications.
Code review, architecture, performance, best practices: we help you build skills while making concrete progress on your projects.
Our involvement strengthens your foundations without creating dependency.
Who are we?
Shiny is a great technology for quickly and easily creating a prototype when you already know R.
But you quickly realize that developing a professional Shiny application involves much more than the R language: first and foremost, you're building a web application.
That's why DATA CHAMP' brings together experts from many web domains to support you in building your Shiny application:
- In R Shiny, of course,
- But also in graphic design, UI/UX, and web integration to create beautiful, user-friendly applications,
- And in system administration and DevOps to help you succeed with your deployments
It's easy to get stuck and lose many development days on a Shiny application as soon as you venture off the beaten path. We can help you.
