With over 14 years of experience in software and infrastructure engineering, I specialize in Data development and Cloud automation (DataOps / DevOps / DevSecOps / SRE).

I assist companies in industrializing and deploying their data platforms, applying the rigor of SRE (reliability, automation, high availability) to the world of Data Engineering.

My areas of intervention:

DataOps & Pipelines: Development, optimization, and security of scalable ETL/ELT pipelines (Spark, Python) and data streams.

Infrastructure as Code (IaC) & Cloud: Automation, provisioning, and management of cloud infrastructures (Azure, Terraform).

Orchestration & Containerization: Deployment and administration of complex clusters and environments (Kubernetes, Docker).

CI/CD & DevSecOps: Building continuous deployment pipelines and integrating security best practices at every stage.

SRE & Observability: Performance monitoring, data quality tracking, and maintaining platform operational readiness.

Committed, pragmatic, and performance-oriented, I develop production-ready, highly secure, and scalable solutions. Let's discuss your needs!
