Daud T.

I build the spatial databases and maps that commercial teams actually run on. Most of my work starts the same way. Parcel data, permits, asset records and demographics scattered across shapefiles, spreadsheets and a legacy system nobody wants to touch. I turn that into one PostgreSQL/PostGIS database with proper keys, constraints and indexing, wire up the ETL in Python so it stays current, and put a map or dashboard on top of it that answers the question in two clicks instead of two days. Track record on Upwork: 57 jobs, 938 hours, 100% Job Success, Top Rated Plus, and a 5.0 rating on every job that has been rated. My longest engagement ran 478 hours over 16 months. What I build: - Spatial databases in PostgreSQL/PostGIS, including PLSS and bitemporal parcel models that stay fast at million-row scale - ETL and data quality pipelines in Python and SQL, scheduled and monitored so nobody has to babysit them - Interactive web maps in Mapbox, and dashboards in Power BI and ArcGIS Online - Site selection, trade-area, territory design, network planning and asset performance analysis - Geocoding, address matching and spatial analysis across large parcel and customer datasets - Custom QGIS plugins and ArcGIS Pro tooling for the workflows your team repeats every week - Cloud deployment with role-based access, logging and backups Typical clients: real estate and land teams working parcel data across US counties, mining and energy operators mapping assets and hazards, and healthcare and retail groups running demographic and competitive analysis. Background: MEng in Geographic Information Systems from Politecnico di Torino, seven years working professionally in GIS, plus research with the European Space Agency on earth observation and remote sensing projects. Based in the Netherlands and used to working across US and Canadian time zones. What clients say: "Daud is the real deal when it comes to geospatial development!" "Excellent work and always responsive. We will definitely work with Daud again. He is a true professional." "Daud did a fantastic job on our trial task, quickly resolving a tricky issue with GIS database management, SQL/Postgres, and ETL workflows." If you have messy spatial data and a decision waiting on it, send me the details. I will tell you straight away whether I am the right fit and roughly what it will take.
