Backend Developer .NET | APIs & System Integrations Specialist | 9 years of experience

Experienced backend developer, I design and deploy robust APIs and .NET architectures for demanding business applications. With a dual technical and sectoral expertise (transport/logistics), I support companies in modernizing their systems and integrating tailor-made solutions.

My playground:

• APIs & Integrations: Design of scalable backend architectures with .NET 8/9, Entity Framework, Dapper

• Architecture & Patterns: CQRS/MediatR, Clean Architecture, SOLID principles

• Authentication & Security: Keycloak, JWT, Azure AD, OAuth2

• Databases: SQL Server, PostgreSQL, complex query optimization

• DevOps & Self-hosting: GitLab CI/CD, Docker, Portainer, Nginx

• Business Applications: dynamic pricing, B2B client management, automated workflows

My approach:

Pragmatic and autonomous, I favor maintainable and scalable solutions. Familiar with the business constraints of transport and logistics, I quickly translate needs into solid technical architectures. I work with professional quality tools (Visual Studio, Rider, ReSharper, StyleCop) to ensure clean and maintainable code.

Technical Stack:

C# (.NET 9/10), ASP.NET Core Web API, CQRS/MediatR, Blazor (Server/WASM), SQL (Oracle, PostgreSQL, SQLite), Docker, GitLab CI/CD, Keycloak, MQTT, Home Assistant (IoT), REST/GraphQL

Context:

Currently a backend developer on a permanent contract in the transport sector, I am available for freelance missions in full remote (evenings/weekends or occasional missions compatible with my salaried activity).
