Freelancer profile translated to English.

Description

Software architect .NET, 14 years of experience — I design sustainable architectures for business applications and SaaS platforms, from startups to large enterprises.

Recent missions and projects: redesign of an industrial production line control system at Schneider Electric, design of a CQRS architecture for a multi-application medical SaaS (Sos Oxygène), complete backend development of a geolocation mobile application (entrepreneurial project — micro-services, WebSocket, PostGIS).

What I bring concretely:

• Architecture design — structuring choices from the outset, CQRS/DDD/Hexagonal depending on the context

• Foundation setup — reference templates, development rules, service organization

• Technical mentoring — skill development, concrete adoption of AI tools (Claude Code, LLM), code reviews, knowledge transfer

• Sustainable delivery — maintainable, tested, documented, transferable code

Stack:

- Backend: C# .NET, EF Core, Node.js

- Frontend: React.js, React Native

- Data & messaging: SQL Server, PostgreSQL, PostGIS, MongoDB, RabbitMQ

- DevOps: Azure DevOps, Kubernetes, Helm, Flux

- Security: OpenID Connect, SAML

Available remotely or in Nice/Côte d'Azur.

Taking over a medical SaaS in critical condition: 3rd failed redesign, ongoing client loss. 4 interconnected applications (doctors portal, technicians mobile app, management intranet, patient space), team of 5 backend developers. Audit of the existing architecture and identification of failure causes: poorly segmented micro-services, double database with inconsistent synchronizations, overly generic APIs. Design of a simplified architecture: single database, shared writing API, dedicated reading API per application (CQRS). Team management: development rules, branch management, code reviews, skill development. Structured knowledge transfer to the next tech lead to ensure continuity.

Result: positive feedback from doctors on the platform, significant time savings for technicians, reversal of client loss trend.
