Alexander was an absolute pleasure to work with, he did everything we asked of him and more. Truly a expert in his subject matter, he provided the guidance we needed and achieved the results we were looking for. I would highly recommend him to anyone.
Great experience working with these Python developers. They successfully completed all tasks with high quality and attention to detail. Communication was always clear, and they were very responsive and responsible throughout the project. I would definitely recommend working with them and would be happy to collaborate again in the future.
We designed our process to make it easy to get started and build trust early on.
Built a full-stack map platform for the founders of izi.TRAVEL, powering tmatic.travel. The system hosts 20 000+ audio tours and 500 000+ stories worldwide. Developed a CMS for curating content, a responsive public map view (Angular, Mapbox) with 2D and 3D modes, and an API for external partners. Includes a dedicated indoor mode for museums and cultural venues to explore audio content without maps. Backend (Java Spring, PostGIS) ensures seamless delivery for travelers and cultural institutions globally.
Developed a crowdmapping platform for Greenpeace’s Recyclemap project, enabling volunteers to map and manage recycling collection points across the country. Built mobile and desktop web apps (Angular, Mapbox GL) for adding, updating, and moderating recycling and ZeroWaste locations. Backend (Python, PostGIS, Martin, H3 clustering) processes OSM data and powers scalable spatial queries. The system empowers communities to contribute and access up-to-date information on waste-free living, supporting thousands of active users.
Designed and built a safety monitoring platform for coal mines and processing plants, aggregating data from diverse sensors (radars, gas detectors, GPS, radio, and more) into a single dispatcher interface. The system provides a digital twin of operations, showing realtime metrics, alerts, and object locations on interactive maps. Developed as a SPA (React, MapLibre) with a microservices architecture (Java Spring, Python, RabbitMQ, Kubernetes, MongoDB, PostgreSQL). Delivered a unified solution that replaced fragmented tools and manual monitoring, enabling faster incident response and improved operational safety.
