Venelin Petkov
Background

About

I started programming at 16 when I got my first computer. I studied biology at the University of Heidelberg and the University of Ottawa, then pivoted to physics — MSc (Diplom-Physiker) from the University of Heidelberg.

Since 2015, I've architected cloud data platforms for major German enterprises — automotive, chemical, retail, sportswear — across AWS, Azure, Databricks, and Snowflake.

I founded Argodis GmbH in 2020 for independent consulting.

Fluent in English, German, and Bulgarian. Dual German-Bulgarian citizenship.

Now

Current Work

Building the Euxine Data Platform — an open-source, EU-sovereign alternative to Snowflake and Databricks. Cost-effective, batteries-included, deployable on European infrastructure via Infrastructure as Code.

Documenting the build in a video series on the Euxine Data YouTube channel.
