PyCon Lithuania 2026

Antanas Baltrušaitis

After 18 years in the data and analytics industry - spanning roles from banking strategy at Nordea to Head of Data at Luminor and Girteka - I made a conscious decision to step out of the corporate world.

Why? Because my skillset doesn't fit a standard job description.

I am a true Generalist in a world that often tries to specialize. I don’t just analyze data; I engineer the pipelines, write the code, design the UI, and map the business strategy. I realized that my ability to manage the entire data journey - from raw SQL to the final user experience - was best utilized in building my own solutions rather than managing narrow slices of corporate infrastructure.

Today, I am fully dedicated to Product Development. I build software where data isn't just a byproduct; it is the core engine.

My flagship product, Scoris, is Lithuania's premier open business data aggregator, built on the belief that public data should be accessible and actionable. I also created Oriux, a weather app designed for precision. Few other massive products about to launch soon.

I bridge the gap between complex data engineering and tangible business value. I am no longer just advising on strategy; I am executing it, line by line and database by database.

Cloud Data Solutions Are Overrated: Building a Pan-European Business Database for Lunch Money
Antanas Baltrušaitis

We are told that modern data engineering requires expensive cloud warehouses and enterprise SaaS. This talk challenges that narrative. I will show how I built scoris.eu - aggregating business data from hundreds of sources across Lithuania, Latvia, Estonia, Finland, and the UK - as a solo developer. Using a purely open-source Python stack (dlt, dbt, Prefect) on cheap infrastructure, I will demonstrate that with the right architecture, you can integrate data at scale without burning cash on the cloud.
