About Hady

Senior freelance .NET developer with expertise in application architecture — 15+ years of experience
backend.
I design and develop distributed backend systems for platforms with high business requirements, delivering
.NET / Azure craftsmanship code (TDD, Clean Architecture, DDD, CQRS) on systems for CAC 40 companies — banking,
luxury, energy, transport.
What I do concretely:
• Design and development of REST APIs, workers, and distributed services in .NET / C# on Azure.
• Business domain modeling (DDD) and implementation of sustainable application architectures (Clean
Architecture, Hexagonal, CQRS).
• Test-driven development (TDD) with unit and integration coverage (xUnit, MSTest, Moq, FluentAssertions).
• Setup and monitoring of Azure infrastructure: CI/CD pipeline (Azure DevOps), secrets management (Key
Vault), observability (Azure Monitor).
• Product collaboration in an Agile environment: User Story breakdown, code reviews,
continuous improvement.
Background: 5+ years IT consulting firm · 5+ years software vendor · 3+ years freelance.
Trilingual French / German (native) · English (full professional). Available for long-term freelance engagement
(3+ years) — full remote or 1-2 days on-site.
