Freelancer profile translated to English.

Description

I design robust and maintainable solutions to transform complex business needs into performant data pipelines, APIs, or microservices. My core expertise lies in Python (Pandas, PySpark), which I use to develop custom, industrialized, and production-oriented processing.

Comfortable in cloud environments (AWS, Kubernetes), I know how to containerize, deploy, monitor, and secure workflows (Docker, Helm, CI/CD, Hvault). I have also worked on mobile interfaces in React Native, backends in Flask/.NET, and databases like PostgreSQL, MongoDB, or SQL Server.

I quickly integrate into technical and business teams, with a real culture of clean, documented, and testable code. My goal: to deliver reliable, scalable solutions adapted to the realities on the ground.
