What Sets Me Apart
With experience across France, Brazil and Germany, I bring a global perspective to every engagement. Before writing code, I invest in shared understanding, using Event Storming and collaborative whiteboard tools to align everyone from developers to product owners, designers and stakeholders around the problem we are solving.
This collaborative foundation leads to systems that are maintainable long after handoff: clean architecture, thorough testing, and infrastructure that teams can operate with confidence.
