What I'm looking for

I'm looking to build reliable data platforms and pipelines where I can solve complex data problems, improve scalability, support analytics teams, and share knowledge through mentoring and technical training.

I've led end-to-end data warehouse and BI platform delivery for SASKI, building its dimensional models, dbt transformations, Apache Airflow orchestration, Superset reporting, Dockerized services, and operational documentation from the ground up.

Across Spotify, PlanA, J. Safra Sarasin, ING, FIAT, and AkSigorta, I've built production data pipelines, real-time processing systems, carbon-emissions calculations, risk software, and reporting platforms using Python, Scala, SQL, cloud services, and distributed data tools.

I've also designed internal tools, trained engineering teams, conducted code reviews, and led external consultants. I enjoy turning complex operational data into reliable, maintainable systems that enable self-service analytics and better decisions.
