Data Analyst & AI Enthusiast · Berlin area

I turn messy data into decisions — and into AI tools that act on them.

I'm Domenic Sawatzki, a data analyst based in the Berlin area. I work with data — analysing it, automating it, building small tools on top of it — and currently learning my way deeper into AI.

About

My path into data wasn't a straight line. I started out in supply chain & process optimization, have been managing projects since 2016, and later worked as a consultant — until I found the thing that really clicked: working with data, and especially preparing it well.

I have a genuine soft spot for high-quality data — clean, well-prepared, trustworthy. What I enjoy most is following the whole process end to end: from raw data, through cleaning and modeling, to the presentation decisions are built on.

Based in the Berlin area, working in German and English. Quietly building and learning — currently going deeper into AI.

Experience

Data Analytics · Lot Internet GmbH

Aug 2024 — present

Lot Internet is a web-crawling & data analytics company. Every day we crawl hundreds of online marketplaces across Europetens of millions of listings daily, and the scale of data I get to work with.

The data I work with powers analytics for some of Europe's best-known online marketplaces and automotive brands — and I'm often in direct contact with them, acting as their account manager as much as their analyst. What I'm known for is a real eye for detail and high standards — I care about getting the data right, not just done.
