Freelancer profile translated to English.

Description

I design high-quality software. From business needs to production, via a proven, iterative, and rapid feedback-oriented agile process.

**Product Discovery**: Mapping usage, revealing implicit business rules, and anticipating edge cases, converging the team towards a common, clear, and testable understanding.

**Domain-Driven Design**: Precise bounded contexts, explicit models, clear separation between business logic and infrastructure.

**Incremental Implementation**: Strict TDD, continuous refactoring, continuous integration and delivery. Each feature is delivered tested and production-ready. Risk reduction and accelerated time-to-market.

**Post-Delivery Monitoring**: Product and technical metrics, user feedback analysis, data-driven adjustments.
