Freelancer profile translated to English.

Description

.NET Senior Developer with 10+ years of experience, I build robust, testable, and maintainable solutions.

**Testing & Quality**: Specialist in Test-Driven Development (TDD) and Behavior-Driven Development (BDD). I have introduced these practices in several organizations and trained teams in their adoption. My expertise in automated testing (unit, integration, E2E) is regularly a decisive factor in winning assignments.

**Architecture**: I design clean and scalable architectures: microservices, distributed systems, messaging (NServiceBus, RabbitMQ). I favor simplicity, separation of responsibilities, and documented technical decisions.

**Clean Code**: Adherent to SOLID principles, Domain-Driven Design, and continuous refactoring. I deliver readable, tested, and easy-to-evolve code.

**Mentoring**: I support junior and senior developers in their skill development: pair programming, benevolent code reviews, technical workshops. I have led weekly knowledge-sharing sessions with several clients.

**Sectors**: Finance, Healthcare, Public Services.
