Freelancer profile translated to English.

Description

Founder of Askmethat and C# engineer specialized in .NET, Blazor, and craft AI agents, I combine imagination and rigor to solve complex technical challenges. Expert in hexagonal architecture, TDD, and autonomous AI agent design, I integrate these skills to create tailor-made, testable, and maintainable solutions aligned with your business workflows.

My approach combines speed of execution, insatiable curiosity, and constructive stubbornness: I never abandon a problem before finding an original or optimized solution. A specialist in Blazor (advanced components, Redux, performance), I also master backend development (.NET, APIs, microservices) and automation through AI agents (orchestration, business rules, tools like Claude Code or Mistral's Vibe).

Passionate about the human brain and collaboration, I challenge conventional wisdom to simplify products, processes, or teams. Open, a good listener, but direct, I prioritize constructive exchanges and solutions without black boxes.

Available for development, architecture, or AI craft missions. Contact me for ambitious projects where innovation and reliability are key.
