Services for Mobility Projects

Maps & Route Planning

Interactive maps, route planners, and location-aware applications. I build everything from a single source — from background data processing to the map your users work with.

Build a new application

Need a new map or mobility application, an internal tool, or a prototype? I build software that fits your needs and provides a foundation to grow on.

Consulting & planning

Which data sources, which architecture, which technology? I explain what makes sense and help with decisions that hold up long-term.

How I Work

Everything from a single source

One point of contact for the entire project: concept, database, interfaces, and user interface. No handoffs between teams, no information lost.

I know your domain

Mobility and geodata have been my focus for years. I know the typical data, standards, and pitfalls — that saves explanation time and protects against expensive wrong decisions.

Senior level, including technical leadership

Over 10 years of experience as a developer. I handle concept, planning, and implementation — and lead other developers in the project when needed.
