The problem you're facing
Your applications talk through flat files, scheduled exports and home-made scripts: every exchange is fragile, every change breaks the integration, and nobody knows a flow failed until a customer reports it.
Our answer
We build APIs that structure your exchanges: clear contracts (OpenAPI), key or OAuth authentication, versioning, logging and monitoring. Integrations become predictable, errors are detected automatically, and evolutions are non-breaking.
What LaMeDuSe takes care of
- API architecture design (REST, webhooks, events)
- Complete, up-to-date OpenAPI documentation
- Authentication and authorisation (OAuth2, keys, JWT)
- Rate limiting and usage protection
- Logging, monitoring and alerting
- Versioning and non-breaking evolution strategy
- SDKs and integration examples
Our methodology
- 1
Product discovery
Workshops with your business teams to turn the need into scope, user journeys and measurable success criteria.
- 2
Design & architecture
Wireframes, technical architecture and documented stack choices: every decision is argued and reversible.
- 3
Iterative development
Regular releases to staging environments, systematic code reviews and demos at every iteration.
- 4
Production & operations
Automated deployment, monitoring, bug fixes and continuous improvements with the same team.
Relevant technologies
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
Our own platforms rely on APIs we develop and operate in European production: we know the real constraints of an exposed API, security, load, monitoring, because we live with ours.
Frequently asked questions
REST for interoperability and simplicity, GraphQL for varied client needs over rich data, gRPC for high-performance internal communication. We recommend based on your context, not fashion.
Systematic authentication (OAuth2, keys, JWT), role-based authorisation, rate limiting, input validation, OWASP Top 10 protection and monitoring of abnormal access. A public API is treated as a sensitive perimeter.
Yes: API audit, rebuilt OpenAPI specification, and documentation that stays current thanks to generation from the code.
Explicit versioning, announced deprecations with transition periods, and automatically tested contracts: a change that breaks an existing client is a regression, treated as such.
