Freelancer profile translated to English.

Description

I use Domain Driven Design (DDD) to identify business domains during the analysis and design phase. I particularly appreciate the CQRS architectural pattern, which captures user intent in commands addressed to the system, but also allows for creating as many data views as there are specialized viewpoints. One of the problems that fascinates me is Disaster Recovery Planning in distributed systems from the perspective of data consistency and the backward propagation of constraints and mechanisms that this imposes on information system design.

My colleagues describe me as a good teacher and kind.
