Back to original languageAbout Alexandre
Tech Lead / Lead .NET with over 20 years of experience in developing high-load SaaS platforms (healthcare, logistics, industry).
Specialized in modern architectures (.NET 8/9, microservices, Azure cloud, React, Blazor, gRPC).
Accustomed to complex contexts: legacy migrations, R&D, team management, and DevOps structuring.
📌 I intervene when:
- A .NET Framework application becomes difficult to maintain
- A migration to .NET Core / Cloud is necessary
- The architecture needs to evolve towards microservices
- The technical team needs a senior lead to structure the project
- Performance or scalability become critical
🚀 Examples of recent interventions
- Complete migration of a SaaS platform from .NET Framework 4.8 to .NET 8, improving maintainability and preparing for cloud scalability.
- Implementation of a microservices architecture with Azure Service Bus and Kubernetes to improve resilience and performance.
- Industrialization of deployments via Azure DevOps (CI/CD), securing multi-environment production releases.
- Technical leadership of teams (code review, standards structuring, migration support).
