I'm Jakub Waller.
I'm a Hamburg-based Data Scientist, working in climate, at shipzero. Because there is no Planet B.
In my free time, you can catch me cycling Planet A, exploring its climate in various warming scenarios (+1.5°, +2.0°…) using my Probable Futures Bot, coding civic Telegram bots, reading an interesting book, or playing the guitar.
A short story so far.
Jakub Waller
For the past 2+ years I've been a Data Scientist at shipzero, helping decarbonise global supply chains — building emission models, ML pipelines and data products that turn messy logistics data into actionable carbon insights. Because there is no Planet B.
Before that, I spent five years at Qimia GmbH on a wide range of Data Science, Machine Learning and Data Engineering projects, then took a year off to travel around our beautiful Planet A. That trip is what convinced me to dedicate the rest of my career to climate and data.
I graduated from the Czech Technical University in Prague with a master's thesis on time series classification using artificial neural networks, with exchange semesters at the University of Waterloo (Canada) and TalTech (Estonia). Earlier roles include Mibcon a.s. (SAP portal apps in Java/AngularJS) and bioinformatics work at the National Institute of Public Health.
