Public transport
Operational experience informs how I think about journeys, passengers, transfers and the practical meaning of timetable data.
About
Operational public transport experience meets hands-on software development.
I work in public transport operations and develop software alongside it. My current focus is data engineering and data-driven software development, particularly GTFS data quality, routing, search, data modelling and understandable visualisation.
Based in Dortmund, Germany ยท open to remote, hybrid and relocation opportunities
Current focus
Data engineering as the primary career direction.
I design and develop IXIT, Keetson and LineManager independently. These projects are working systems, and parts of them can be tested directly on this website.
I am open to software development roles with a strong data or mobility focus. System architecture is a long-term direction that I am actively developing through practical projects.
Software development
Java, Kotlin, JavaScript, PHP, SQL and Android development support practical products rather than isolated experiments.
Data systems
GTFS preprocessing, validation, normalisation, feed fusion, data modelling and visualisation are central to the current work.
