I build production-grade data pipelines for location data, the kind that survive real scale, messy sources, and senior technical review. Most data engineers can't work in GIS, and most GIS specialists can't ship reliable pipelines. I do both, which is exactly what location-heavy projects need. If you're working with geographic data, satellite or aerial imagery, parcel and infrastructure records, point-of-interest datasets, anything tied to coordinates, I turn it into clean, queryable, automated systems instead of one-off scripts that break the moment the source changes. What I do: - Geospatial ETL pipelines (PostGIS, geopandas, rasterio) that ingest, clean, and structure spatial data at scale - Remote-sensing and imagery workflows, sourcing, tiling, and organizing aerial/satellite data across many locations - Web scraping and data extraction (Playwright, BeautifulSoup) with proper deduplication, rate-limit handling, and validation - Config-driven, schema-adaptive pipelines that adapt to new sources without a rewrite - Spatial APIs and mapping backends (FastAPI, PostgreSQL/PostGIS, Leaflet) How I work: I diagnose the real bottleneck before writing code, I'm honest about tradeoffs (including when the hard part is data cost or source limits, not engineering), and I build for handoff, documented, maintainable, and yours. Proof: - Processed 6M+ US building permit records through a config-driven ETL pipeline (ConstructIQ) - Built a nationwide vendor directory of 4,400+ records via multi-phase scraping and enrichment (EventStarted) - Mapped fiber infrastructure across Lagos State in PostGIS (UDIGAP) - B.Sc. in Surveying & Geoinformatics — the geospatial fundamentals behind the engineering Tell me what your data looks like and what you need out of it, and I'll map the approach against your constraints before we talk price.

Frequently asked questions
Is hiring a QGIS specialist worth it?
Hiring a QGIS specialist can be worth it when your project depends on turning location-based data into useful outputs such as maps, spatial analysis, or decision-ready geospatial deliverables. GIS systems analyze and display geographically referenced information, and QGIS provides an open-source platform for creating, editing, visualizing, analyzing, and publishing spatial data without licensing costs.
It is usually most worthwhile when you can clearly define the problem, inputs, and expected outputs. Upwork's hiring and scoping guidance show that clearer deliverables, tools, and timing lead to better-fit proposals, while the U.S. Bureau of Labor Statistics projects 6% growth for cartographers and photogrammetrists from 2024 to 2034.
What should I include in a QGIS job post?
To hire a QGIS specialist, your job post should include scope, deliverables, data details, timeline, background requirements, and budget model. Spell out what you need created or analyzed, what data you have available or whether data needs to be sourced, what output formats you require, your timeline, any industry context that affects cartographic style or analysis approach, and whether you prefer hourly or fixed-price billing.
Should I choose hourly or fixed-price for QGIS work?
For QGIS work, use fixed-price contracts for well-defined outputs such as a specific map set, spatial analysis package, or documented deliverable where scope can be approved at milestones. Choose hourly contracts for evolving support, recurring updates as data changes, or exploratory work where scope may shift based on findings. Fixed-price projects give more budget control when deliverables can be defined and approved upfront.
How do I evaluate QGIS freelancers?
To evaluate QGIS freelancers, prioritize industry fit, similar project experience, client feedback, and work samples. Review their portfolio for projects that match your data types, analysis methods, and cartographic needs. Check client reviews for feedback on quality, communication, and ability to meet deadlines.
What data do I need to provide to a QGIS specialist?
The data you provide to a QGIS specialist depends on your project scope. At minimum, share vector files (shapefiles, GeoJSON, GeoPackages) or raster files (GeoTIFF, satellite imagery) that contain the geographic features or surfaces you need analyzed or mapped. Also clarify the coordinate system or projection, any attribute data or tables that need to be joined, and whether data needs to be sourced, cleaned, or validated before analysis begins.
If your data is incomplete or needs preparation, discuss this during the evaluation and interview stages so the freelancer can scope data cleanup, sourcing, or quality checks into the project plan. Be clear about what you can share before the contract starts and what will only be shared after the contract is in place.
