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
Mapping foundation
OpenStreetMap, often shortened to OSM, is an open geographic database created and maintained by a global contributor community. It contains roads, buildings, addresses, paths, land use, public transport features and points of interest. Companies use this data to power maps, routing tools, logistics workflows, asset directories and location-aware products.
Data and tooling
Working with OSM involves more than displaying a map. Specialists use the iD editor or JOSM for data work, Overpass API for targeted queries, and Nominatim for geocoding. Tile services, vector formats, import pipelines and validation workflows matter when a product needs reliable, current geographic information.
- Design data extraction and update workflows
- Configure geocoding, search and routing components
- Connect OSM data with PostGIS and spatial services
- Prepare map layers for Leaflet or MapLibre
Products and use cases
OSM supports customer-facing maps, delivery planning, mobility services, field operations and infrastructure monitoring. It also fits internal tools that need searchable locations without depending on a single commercial map provider. In Germany, specialists may support transport, logistics, energy, retail and public-sector projects while adapting collaboration to local teams and language needs.
When expertise matters
Companies bring in freelance expertise when a mapping initiative must move from a prototype to a dependable service. The work may include selecting suitable extracts, cleaning imported data, building spatial queries, tuning map rendering or reviewing licensing and attribution requirements. Remote collaboration works well when data contracts, acceptance criteria and deployment access are clearly defined; on-site workshops can help with domain-heavy projects.
Quality signals
Strong professionals understand both geographic data and software delivery. They can explain the difference between source data, rendered tiles, geocoded results and routing output, then choose an appropriate workflow for each. They also test edge cases such as incomplete addresses, changing road networks, duplicate features and inconsistent tagging instead of treating the map as a static image.
Sustainable delivery
A robust OSM project plans for updates, community changes and operational ownership from the start. Experts document data sources, attribution, import decisions, API limits and fallback behaviour. They can also establish monitoring for failed updates, stale tiles and altered schemas, helping teams keep location services useful as their products, territories and business requirements change.
Frequently asked questions
Questions about OpenStreetMap? Start with the answers below.
Companies use OpenStreetMap for interactive maps, geocoding, routing, logistics planning, mobility services and location-aware business applications. Its open data can also support internal tools for assets, sites, service areas and field operations.
OpenStreetMap offers openly licensed geographic data and a broad community contribution model, while commercial providers commonly bundle data with hosted APIs, support and service guarantees. The right choice depends on coverage needs, update workflows, licensing obligations, routing quality and the level of infrastructure a company wants to operate itself.
A strong OpenStreetMap professional often works with PostGIS, spatial databases, GeoJSON, vector tiles, Leaflet, MapLibre, geocoding and routing services. Experience with cloud deployment, data pipelines, API design and frontend integration is useful when the map is part of a larger product.
The required depth depends on the scope. A simple map display may need focused frontend and tile knowledge, while imports, large-scale queries, routing or operational data updates require a professional who understands OSM data structures, spatial performance and maintenance risks.
Yes, much of OpenStreetMap work can be completed remotely through shared repositories, documented data workflows and cloud environments. On-site sessions can still help when specialists need to understand local operational processes, mapping conventions or requirements from German-speaking stakeholders.
Ask the professional to explain data provenance, update handling, attribution, API usage and validation methods. For OpenStreetMap applications, review how they handle incomplete addresses, changing features, query performance and failures rather than judging only the visual appearance of the map.
Yes, OpenStreetMap data can support production applications when the company selects appropriate data and hosting arrangements. Production readiness requires clear usage policies, reliable update pipelines, suitable tile and geocoding services, monitoring and a plan for changes in coverage or infrastructure.
Freelancers may deliver map interfaces, data imports, Overpass queries, geocoding workflows, PostGIS models, vector tile pipelines or routing integrations. An experienced OSM specialist should also provide documentation, licensing and attribution guidance, deployment notes and a clear handover for ongoing maintenance.
