Meet the team

This is the team behind openrouteservice - a colourful mixture of forward thinking minds from different domains

Openrouteservice is maintained by Heidelberg Institute for Geoinformation Technology (HeiGIT) group and is supported by the Klaus Tschira Foundation (KTS) Heidelberg. It is part of the GIScience Research Group at the Department of Geography, within the University of Heidelberg. Its objective is to facilitate the transfer of knowledge and technology from academia to practical applications and professional services. The focus lies on the analysis, refinement, enrichment and usage of big spatial data from the crowd for innovative applications and services.

Adam Rousell

Core Engineer

While implementing all different kinds of handy new features to the openrouteservice core, Adam also handles everything around the openrouteservice geocoding services and is terribly comfortable in debugging, tweaking and consuming elastic search databases. And he loves restricting borders!

Matthias Marquardt

Core Engineer

With about a myriad of hours of java engineering up his sleeve, Matthias helps openrouteservice at its very core. And, by the way, he actually loves cycling, so you can be quite certain that you will be using most suitable ways you can imagine!

Andrzej Oleś

Core Engineer

Andrzej studied computer science and earned his PhD in theoretical physics. Today he is working with us especially on graph algorithms to make openrouteservice find your optimal route in an even shorter amount of time. By the way, he is also a pretty experienced R developer – not many of them are around here in Heidelberg!

Nils Nolde

Python Engineer

Nils comes from the domain of Geophysics but luckily enough enjoys working with anything within the spatial domain. He use to work for Zalando in the field of logistics and brings quite some wisdom to the team of openrouteservice. By the way, he is also the author of the notorious OSMtools QGIS plugin!

Alexander Zipf


Alexander is chair of GIScience (Geoinformatics) at the University of Heidelberg. He started openrouteservice back in 2008 and promised to keep innovative services running until the present day.

Sabrina Marx

DevOps Engineer

Sabrina is genuinely fascinated by docker and containerized setups and helps us make the openrouteservice infrastructure stable and scalable. To this end, feel free to message her if you don’t get a response from our API – just kidding.

Hendrik Leuschner

Core Engineer

Hendrik comes from the domain of physics and has profound knowledge and experience in developing spatial algorithms and application programming interfaces. His speciality is making these scalable and performant for large datasets.

Amon Santana

Web Engineer

Amon is one of those polyglots in the world of web development. Take your pick: single page applications, php frameworks or even web design, he’ll get any of it done in time. And in quality. Our openrouteservice community is happy to have him on bord and so are we.

Amandus Butzer

Web Engineer

Most of the time Amandus is implementing new features and fixing bugs on Additionally he takes care of our documentation and api examples.

Julian Psotta

Core Engineer

Julian loves test driven development and implements handy new features to the openrouteservice core. Feel free to contact him if you have any great ideas, he will love to hear from you!

Isabell Klipper

Python Engineer

All of our python showcases are taken care by Isabell. The stories come from our users while she is the engineer making precious jupyter notebooks out of them!

Sascha Fendrich

Core Engineer

Sascha fancies tricky bits and bytes and implements state of the art algorithms to the openrouteservice routing engine to help the services scale.

Takara Baumbach

Core Engineer

Takara not only loves instruments. He speaks Java fluently and takes care of new and fancy features in the openrouteservice API.

Tahira Ullah

Python Engineer

With profound Python and PostGIS skills Tahira studies new datasets to incorporate into the openrouteservice ecosystem.
