About

Hi, I’m Florents! Friends call me Flo. I was born 33 years ago. After living the first five years of my life in Visokë, Albania, my family moved to Salamina Island, Greece, where I grew up. I now split my time between Athens and Salamina.

I self-identify as a data generalist with 10+ years of experience across the data stack.

My work sits at the intersection of database engineering, AI, web crawling, and data journalism, often blending research, engineering, and leadership along the way.

I’m also PostgreSQL developer with hands-on experience in Postgres internals, extension development, and custom types and functions — from low-level C to high-level SQL and PL/Python.

My open-source software projects are available on github.com/Florents-Tselai.

Some companies I have worked for or consulted for include BCG, Deutsche Telekom, BASF, GfK, XING, BMW, and Advantest, among others. My professional profile is on LinkedIn

I also do pro-bono work for non-profits.

If you think we could work together or would just like to talk, let’s talk!

diofanti.org

If you’re a Greek journalist, politician, or concerned citizen, you may have come across diofanti.org, a free and public tool I’ve created that tracks government spending in Greece. Here’s a demo video showcasing it.

I try to read as many books as possible. I’m generally interested in the evolution of military strategy and the history of war, as well as the evolution of trade throughout human history.
