MOBILITY | BOOKING PLATFORM AND MOBILE APPS
The need: Two transport brands needed different booking experiences without maintaining separate systems for orders, drivers and prices.
What we built: A shared platform connects two branded websites, customer and driver apps, and an operator portal. Customers can book rides or airport transfers and follow a driver on a live map. The operator portal brings dispatch and statistics together. Stripe supports payments.
- Websites and mobile apps
- Booking and ride workflows
- FastAPI and PostgreSQL
- Shared backend and data
- Operator portal
- Dispatch and statistics
Technology: Next.js, React Native / Expo, Python / FastAPI, PostgreSQL, Stripe, Leaflet / OpenStreetMap
Business value: Bookings from two brands feed a common operational system while each brand keeps its own customer experience.

Can S.
Last position:
Platform Engineer at ClimateChoice
In a lean, execution-focused environment, I took ownership beyond a narrow engineering lane, shaping and implementing systems across backend, data, and infrastructure. Partnered directly with the three founders in a fast-moving, high-stakes environment, turning strategic priorities into concrete technical decisions and production outcomes.
- Owned core platform development across backend (Django/Rest Framework/Postgres), ETL (Python/Dagster), infrastructure (Terraform/Kubernetes/AWS), and frontend (typescript/react) for a climate-tech SaaS product, driving continuous cross-stack development across five repositories from October 2021 to this day.
- Architected and owned a standalone internal Python scoring framework for CRC assessments, using YAML-driven rules and metaprogramming to enable non-technical users to define complex evaluation logic without hardcoded implementations.
- Built and stabilized ETL and scraping pipelines using Dagster and Scrapfly, improving document ingestion, tagging, retry behavior, deployment flow, and operational resilience.
- Contributed to platform modernization and reliability through Django/Python upgrades, Postgres/RDS and EKS changes, CDN/TLS updates, test and performance improvements, and observability hardening.
- Drove backend engineering for product features, translating requirements into technical specifications, API contracts, data structures, and scalable implementation plans.

About the technology
What OpenStreetMap provides
OpenStreetMap, often called OSM, is an open, community-maintained geographic database. It contains roads, paths, buildings, addresses, points of interest and many other map features. Companies use its data to power interactive maps, location search, routing, logistics tools and spatial analysis without relying on a closed map provider.
Where it is used
OpenStreetMap supports products and services that depend on current, detailed location data. Its flexible data model works for public services, mobility, retail, logistics, real estate, travel and humanitarian projects.
- Interactive maps for websites and mobile applications
- Address search, geocoding and route planning
- Fleet, delivery and field-service operations
- Site selection, territory planning and spatial analysis
Data and tooling
Professionals work with the OpenStreetMap data model, tags, relations and change history. Common tools include the Overpass API for targeted queries, Nominatim for geocoding, and tile services based on technologies such as MapLibre GL JS, Leaflet or OpenLayers. Depending on the project, specialists also use PostGIS, GeoJSON, vector tiles and GDAL.
When expertise matters
Companies often bring in freelance expertise when they need reliable map data in a product but do not have strong geospatial skills in-house. Specialist support is valuable during data imports, migration away from proprietary map services, custom rendering work and the design of scalable location workflows.
- Select suitable OpenStreetMap extracts and update processes
- Build and secure geocoding or routing integrations
- Design map interfaces for desktop and mobile use
- Validate data quality, licensing and attribution requirements
What strong specialists deliver
Strong professionals understand both the data and the application around it. They can distinguish between raw OpenStreetMap data, rendered map tiles, geocoding results and routing output, then choose an architecture that fits the use case. They document data sources, update schedules, attribution and operational responsibilities clearly.
They also test edge cases such as incomplete addresses, disconnected roads, restricted access and changing tags. Practical experience with caching, API limits, privacy, accessibility and performance helps turn a map prototype into a dependable service.
Working across Germany
OpenStreetMap projects can be handled remotely when requirements, data access and review processes are clear. On-site collaboration in Germany may help when mapping workflows connect to local operations, transport networks or public-sector teams. German and English communication can both matter, especially when specialists coordinate with local stakeholders or review regional place data.
Frequently asked questions
Questions about OpenStreetMap? Start with the answers below.
OpenStreetMap is used for interactive maps, address search, routing, asset tracking and location analysis. It can support customer-facing applications as well as internal tools for logistics, mobility, retail and public services.
OSM offers openly licensed geographic data and a highly detailed community editing model, while commercial providers typically bundle data with hosted APIs, support and service-level commitments. The right choice depends on coverage, update needs, routing quality, licensing, operational control and the amount of infrastructure a company wants to manage.
A strong OpenStreetMap specialist may also work with GIS, PostGIS, GeoJSON, vector tiles, Leaflet, MapLibre GL JS or OpenLayers. Experience with Nominatim, Overpass API, routing engines, cloud infrastructure and data pipelines is useful for production systems.
OpenStreetMap work can range from a focused map integration to a complex geospatial platform. A simple display may need limited specialist input, while custom imports, tile infrastructure, routing, geocoding or large data updates require deeper experience in data modeling and operations.
OpenStreetMap projects are often suitable for remote collaboration when access, requirements and review responsibilities are defined clearly. On-site work in Germany can be useful when the project involves local field teams, transport operations or workshops with German-speaking stakeholders.
OpenStreetMap data is available under the Open Data Commons Open Database License, with attribution and other obligations that depend on how the data is used. A capable specialist should explain attribution, database rights, produced works and the implications of combining OSM data with other sources.
Look for a portfolio showing real map interfaces, geocoding, routing, data processing or tile delivery rather than visual examples alone. Ask how the freelancer handles incomplete data, updates, caching, attribution, privacy, performance and failures in external services.
An OpenStreetMap freelancer may deliver a map component, data import, geocoding or routing integration, a PostGIS workflow, custom tiles or operational documentation. The expected output should include clear data sources, update processes, attribution requirements and tests for important geographic edge cases.
