Summary
🤩
RockstarPeter Johnson is a seasoned software architect and founder with 15 years of experience, currently serving as CTO of Geocode Earth in Berlin where he commercializes the open-source Pelias geocoder. Since 2014 he has led design and engineering of information retrieval and geocoding systems used by transit agencies, local governments, and businesses to deliver high-quality location experiences. As the creator and core maintainer of Pelias, he combines hands-on backend, DevOps and test automation expertise—improving API caching, autocomplete, and Docker infrastructure—to keep global geodata accurate and accessible.

Known for practical engineering and public speaking, he balances technical leadership with active community stewardship and a knack for turning complex spatial problems into reliable production services. Outside work he’s a Kiwi father who’s quietly spent years building some of the most widely used open geocoding components on GitHub.
