Can Savastürk
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
Core use
OpenStreetMap, often called OSM, is the open map dataset many teams use for location-aware products. Companies bring in specialists to turn map data into clear user experiences, internal tools, and services that depend on accurate places, routes, and boundaries. It fits products that need flexible map data without locking into one vendor.
Typical work
- Custom map views for web and mobile products
- Geocoding and reverse geocoding flows
- Routing, delivery, and fleet support
- Boundary, POI, and address data handling
- Data import, cleanup, and enrichment
Strong professionals know how to choose the right tiles, tags, and map style for the use case. They also understand how to combine OSM data with other sources when a product needs better coverage, sharper search, or more local detail.
Ecosystem
OSM work often involves tools around data editing, rendering, routing, and search. Common stacks include tile servers, styling tools, geospatial databases, and services built on top of the core map data. Good specialists can work across this stack and keep the mapping layer reliable as the product grows.
When to hire
- A product needs map data tailored to a specific country or city
- Search, routing, or address lookup feels inconsistent
- A team wants to move away from a closed map provider
- Existing OSM usage has data quality or styling gaps
- A release depends on accurate spatial data handling
In Germany, freelance experts are often useful when local product teams need hands-on help without adding a full-time specialist. Remote collaboration works well for most OSM tasks, while on-site sessions help when mapping logic must align with operations, logistics, or field work.
What strong specialists do
Good OpenStreetMap professionals do more than place markers on a map. They check data quality, understand tags and relations, and know how map content affects search, routing, and display. They also document their decisions so product, data, and engineering teams can keep the map layer consistent.
Common challenges
OSM projects fail when teams treat map data as a static background. Real work often includes version changes, local edits, missing tags, and tricky edge cases in addresses or routes. Experienced specialists reduce that risk by testing with real user flows and validating data against the product goal.
Frequently asked questions
Questions about OpenStreetMap? Start with the answers below.
OpenStreetMap is used for maps, location search, routing, delivery planning, asset tracking, and other products that need geographic data. Teams also use OSM to render custom map styles or to build internal tools for field operations and logistics.
OpenStreetMap gives teams open map data they can adapt, which is different from relying on a closed provider. Google Maps and Mapbox can still be the right choice for some products, but OSM is often preferred when data control, custom styling, or mix-and-match tooling matters.
A strong OpenStreetMap specialist usually knows geospatial data, tagging, tiles, geocoding, and routing basics. Skills with PostGIS, GeoJSON, QGIS, Leaflet, or OpenLayers are often useful because OSM work rarely stops at the map itself.
A simple OSM integration may only need someone who can wire up map display and basic location search. More complex work, such as routing logic, address normalization, or country-specific data cleanup, benefits from a specialist who has handled production data before.
Yes, OpenStreetMap work is often handled remotely because most tasks are data, code, and configuration driven. For teams in Germany, remote collaboration is common, but on-site time can help when the map setup must reflect local operations or field workflows.
Look for practical work on OpenStreetMap, not just map display screenshots. Good signs include clear tagging decisions, testing with real geographic edge cases, readable documentation, and an ability to explain trade-offs between coverage, accuracy, and speed.
OpenStreetMap projects often struggle with incomplete data, inconsistent tags, and routing or search behavior that does not match the product need. A good specialist spots these issues early and sets up checks so they do not come back after launch.
Bring in OpenStreetMap expertise when the team needs fast progress on a map-heavy feature, a migration away from another map provider, or help with hard data problems. Freelancers are also useful when the internal team needs a specialist for a limited phase, not a permanent role.
