À propos de Jonathan

Most data platforms don’t fail because of technology.
They fail because of poor design, lack of ownership, and uncontrolled costs.

I help companies build or scale their data platform while reducing Snowflake and BigQuery costs.

Over the past 8+ years, I’ve worked on data platforms in banking, pharma, and media environments, handling large-scale data pipelines and complex business requirements.

I take ownership from design to production.

What I bring:

· End-to-end data pipelines (batch & streaming)
· Modern data stack (Snowflake, BigQuery, dbt, Airflow, Spark)
· Data platform architecture (cloud, Kubernetes, CI/CD, Terraform)
· Cost optimization (FinOps mindset applied to data platforms)

Typical impact:

· Pipelines processing TB-scale data daily
· Improved performance, reliability, and delivery speed
· Reduction of Snowflake / BigQuery costs (20–50%)

I focus on building data platforms that scale — technically and financially.
