Freelancer profile translated to English.

Description

As a software engineer, I support companies on projects with high technical stakes: modernization of legacy systems, distributed architectures, and large-scale full-stack applications.

I have worked on critical platforms (charging infrastructure for electric vehicles, real-time banking systems) handling high volumes of data, with strong requirements for reliability, performance, and maintainability. I notably participated in the complete rewrite of a banking IS, based on DDD microservices, Kafka Streams, and SQL query optimizations to support millions of daily operations.

My approach is pragmatic: clean architecture, Domain-Driven Design, technical decisions aligned with business challenges. I am involved in design, redesign, as well as securing and evolving existing systems.

I regularly share my feedback during conferences like Devoxx France, Voxxed Days, Sunny Tech, and DevFest (AI-assisted testing, strategies around legacy code). To learn more: craft-agents.com
