Michael D.

Senior full stack .NET developer with 12 years of experience, I am involved from technical scoping to production deployment, both as team reinforcement and as a lead. Backend, frontend, business rules, persistence, deployment: I handle the complete chain.

My foundation is solid on the backend: .NET Core / .NET Framework, ASP.NET Core (and MVC/Forms/VB.NET on historical applications), SQL Server, all tooled with Git and CI/CD Azure DevOps / ArgoCD.

On the frontend, I am particularly comfortable with native TypeScript, JavaScript, and HTML/CSS, with experience in React on my personal projects; I have also worked in an Angular environment.

Over the years, I have supported projects for several major clients, such as the development of a product-based platform (multi-tenant subscription process). I have led structuring migrations on historical applications (VB.NET to C#, ASP.NET Forms to MVC), then contributed to a refactoring on a modern stack, microservices, and Domain Driven Design, before re-injecting these practices into the existing system to reduce technical debt. This dual culture, legacy and modern, allows me to evolve a system in production without breaking it.

What sets me apart is a genuine focus on quality, Clean Architecture, CQRS, testing, code reviews, all in service of maintainability, reliability, and security, without ever losing sight of pragmatism and the end-user. I also have experience in a Tech Lead role: scoping, architectural choices, developer mentoring.

I have built specialized expertise in finance and savings, particularly in life insurance processes (subscription, arbitrage, payment, redemption). This is an asset if your project involves these topics, but my technical foundation applies to any web product.

Available for hybrid missions in the Île-de-France region or fully remote.
