I am a long-term member of the OpenStreetMap community and have been developing software for the OSM for more than a decade.

What I work on

I am maintainer of the following projects:

• Nominatim
  An open-source geocoder for OpenStreetMap data. It powers the search box on osm.org and is run by many companies as a privacy-maintaining alternative to commercial cloud-based geocoders.
• Photon
  An ElasticSearch-based frontend to Nominatim which also supports search-as-you-type. It comes with ready-to-use database dumps which allow to get your own geocoder running in a matter of minutes.
• osm2pgsql
  osm2pgsql loads OpenStreetMap data into a PostgreSQL database. It is the base for Nominatim and many rendering applications.
• pyosmium
  Light-weight Python-bindings for libosmium, a C++-library for fast processing of the different OpenStreetMap data formats.
• waymarkedtrails
  A website that shows hiking, cycling, riding and skiing routes from OpenStreetMap. Made by a mapper for mappers but also good to plan your next outdoor adventure.

Sponsoring

Your monthly donation helps with the daily maintenance of the projects mentioned above. What is more, with your sponsorship I can do open-source development as a full-time job. And this gives me truly the time to advance the project, improve performance and add long-requested features.

If recurring sponsorship is not for you, then a one-time donation helps as well. If you are rather interested in specific feature development or need a support contract, have a look at Nominatim's funding page.
