Sustainable digital gardens

Designed to last and evolve

Solutions designed to stand the test of time.

Thoughtful architecture, rigorous code, and measured technical choices enable platforms to evolve without constant rebuilding, while maintaining performance, accessibility, and stability.

Controlled performance

Large-scale platforms with controlled operating costs and stable performance over time, in production for several years.

Accessibility integrated from conception

Projects designed and delivered according to WCAG 2.2 AA standards, tested with assistive technologies and documented to ensure lasting compliance.

Lasting relationships

Long-term support, stable teams, and systems maintained and enhanced over several years, without quality loss or repeated rebuilds.

Sustainable technical principles

Sustainable serverless architecture

  • Serverless functions and REST API for native scalability
  • Global distribution via CDN
  • Resilient and performant NoSQL storage
  • Automated and reproducible deployments
  • Decoupled architecture favoring evolution without rebuilding

WCAG 2.2 AA accessibility

  • Development compliant with WCAG 2.2 AA requirements
  • Testing with assistive technologies and keyboard navigation
  • Readability and contrast optimization
  • Semantic HTML and mastered ARIA landmarks
  • Documented and verifiable compliance

Rigorous and maintainable code

  • Limited and justified dependencies
  • Continuous, clear, and exploitable technical documentation
  • Automated tests covering key scenarios
