Description

Hello,

I am François, a Cloud Architect / DevOps Engineer specializing in AWS and data & machine learning infrastructures.

I help R&D and data teams design reliable, performant, and cost-effective cloud environments, while fostering fluid collaboration between developers, architects, and business stakeholders.

My work focuses on automation (Terraform, GitHub Actions, CI/CD), cross-account security (IAM, OIDC, Landing Zones), and the implementation of data & ML pipelines (S3, SageMaker, Databricks, Batch, Airflow).

I design KISS, scalable, and economical solutions, always keeping a FinOps and long-term vision.

On a human level, I am recognized for my clear communication, proactivity, and ability to quickly integrate into a project.

I learn quickly, I quickly understand business and technical challenges, and I enjoy building connections between teams so that technology truly serves the project's vision.

💼 Areas of Expertise:

AWS Cloud / Data / ML Architecture & Deployment

Infrastructure as Code (Terraform, CI/CD, GitHub Actions)

Data Lake, S3 Catalogs & ML Pipelines

FinOps & Cost Optimization

Multi-Landing Zone Security (OIDC, IAM)

Data Migration (Azure → AWS, DataSync, Airflow)

I am looking for ambitious, concrete, and meaningful projects where technology combines with rigor and curiosity.

Looking forward to discussing your cloud needs and data challenges.

— François
