The problem you're facing
Many React applications age badly: thousand-line components, state shared through side effects, obsolete dependencies, and a bundle that takes three seconds to load on mobile. The fault isn't React's : it's the absence of architecture.
Our answer
We develop with architectural discipline: decomposed, testable components, state management proportionate to the need (not systematic), server rendering where it helps (Next.js), and measured performance. The result is a fast, readable application your teams can maintain.
What LaMeDuSe takes care of
- Front-end architecture adapted to the product (React, Next.js)
- Decoupled, tested and documented components
- Proportionate state management (no systematic over-engineering)
- Performance: server rendering, bundle splitting, tracked metrics
- Accessibility and responsive design
- Typed API integration (TypeScript end to end)
- Optional training for your teams
Our methodology
- 1
Context audit
Understanding of how you use the technology: volumes, constraints, existing setup and goals.
- 2
Tailored architecture
Argued recommendations, adapted to your context rather than copied from a textbook case.
- 3
Implementation
Deployment, configuration and industrialisation by teams who run the same stack in production.
- 4
Skills transfer
Documentation, reviews and knowledge transfer so your teams gain autonomy.
Relevant technologies
Security
Every implementation follows our hardening standards: baseline configuration, managed secrets, monitoring and backups.
Hosting & infrastructure
We operate these technologies on our own European infrastructure: expertise is proven by operations, not by certification.
Maintenance
Version tracking, security watch and support by the teams who administer the same stack every day.
Why LaMeDuSe
Our own platforms, this public site included, are developed in React and Next.js by our teams. We live with the architectural choices we make for clients: proof by usage.
Frequently asked questions
Next.js for most web projects: server rendering, SEO, routing and performance included. Plain React for internal applications behind authentication, where SEO doesn't matter. We choose based on usage, not fashion.
For any application meant to last, yes: types document the code, prevent entire classes of bugs and ease handover to other teams. We develop in TypeScript by default.
Yes: code audit (architecture, dependencies, debt), honest assessment, then a takeover plan : stabilisation, dependency modernisation, and evolution. We also take over applications others left behind.
By measuring it: tracked Core Web Vitals metrics, bundle splitting, server or static rendering per page, and testing on real mobile devices. Performance isn't a checkbox : it's a tracked budget.
