Tim Lietzow

Who I am

I am Tim. Born in Dorsten, raised in Gahlen, a small village in North Rhine-Westphalia. I moved north for my studies: I study computer science and am doing my apprenticeship as an IT specialist for application development alongside it (a German “triales Studium”). Both are still ongoing. I am not a finished professional, I learn something new every day. Programming is my passion.

What I do

Data science is my main field. I analyse data, build models, automate processes. AI is a tool here, not a selling point: if a practice wants to know why so many appointments fall through, I look at the no-shows first, and then say whether that needs a model or whether a reminder text will do.

At my company I work in the AI team. That means forecasts such as demand forecasting, language models that condense long reports down to what matters, and making sure it all runs reliably and cheaply, with good prompting and prompt caching.

I build websites because that is where you see fastest whether an idea works: built today, online tomorrow. My focus is still on data and software.

How I work

Almost every project starts with an idea. Then comes a first attempt: not perfect, but a proof of concept that lets us see together whether the idea holds up. Only after that does it get polished and robust. The best part is the variety, a forecast today, a website tomorrow, a script that saves someone work every week the day after.

Why Buxtehude?

Because I live and work here. I am not from here, but I like it here. For businesses in Buxtehude, Stade and Hamburg I can be there quickly when a conversation at the table beats an email. In that conversation I explain my ideas, listen to your wishes and show how we can make them happen.

Why cherry blossoms?

Because I love Asian culture — from indigo dyeing to the samurai to anime. This year I was in Taiwan, and that made the love even bigger. The cherry blossom on this site is my small bow to it. And because I am a data scientist, it is made of data points.
