ABOUT

I'm Tahirintsoa Mamitiana. Data engineer in Paris, I design and run data pipelines and cloud architectures on AWS and GCP, with Airflow, ClickHouse, dbt, Kubernetes or Terraform depending on what the project needs. I grew up in Fianarantsoa, in the Malagasy highlands, before moving to France. This blog is a set of technical field notes, because I'd rather share what breaks and what works than a list of skills.
