Focusing on Data Science, Spatial Analytics, and GIS Solutions.
Freelance & GIS Solutions
I offer spatial data management, custom mapping, and analytics services to clients around the world — available on the two platforms below.
Fast, focused GIS gigs — from a single map to a full spatial database.
- Spatial Analysis & geoprocessing
- Custom cartography and thematic maps
- Geospatial database management (PostGIS)
- Data cleaning and coordinate conversions
Longer engagements — analysis pipelines, dashboards, and research support.
- End-to-end spatial data pipelines
- Python & SQL automation for GIS workflows
- Interactive maps and analytics dashboards
- Remote sensing and satellite data processing
Earth Sciences, Information Systems, and a Guitar in the Corner.
I'm an undergraduate researcher studying Geological Engineering at Hacettepe University and Management Information Systems at Istanbul University. That mix — Earth sciences on one side, tech and MIS on the other — is what shapes how I approach spatial data: I look at the ground and the data on top of it with the same lens.
My focus is building a hybrid technical portfolio around spatial data analytics: wrangling geospatial datasets in Python and SQL, modeling them in PostGIS, and turning the results into clear maps and dashboards with ArcGIS and QGIS.
Outside the terminal, I'm a musician. I play guitar and piano, sing, and spend a lot of time on music production — same instinct as the data work, really: patterns, layers, and making them sit right together.
