Hire the Best Geographic Information System (GIS) Developers
in Turkey

I am a Geospatial Data Engineer and Python Developer specializing in turning complex spatial problems and unstructured data into clean, automated, and scalable solutions. With a strong engineering foundation, I don't just write code; I design lightweight, cost-effective pipelines that eliminate manual work and deliver precise analytical insights. Whether you need to extract thousands of records from confidential PDFs, build a live-updating interactive web map, or enhance satellite imagery using Deep Learning, I deliver engineering-grade results. My Core Capabilities: -Geospatial Engineering & Web Mapping: Building live, interactive web applications (Streamlit, Folium) for real-time spatial data tracking. Advanced spatial analysis, coordinate transformations, and database management using QGIS and PostgreSQL/PostGIS. -Data Automation & ETL Pipelines: Developing robust Python scripts (using RegEx, Pandas) to automatically parse, clean, and extract data from messy, unstructured sources (like official PDFs or raw text) into structured Excel files or BI dashboards. -Remote Sensing & Computer Vision: Designing custom data pipelines (Rasterio, OpenCV) and training Deep Learning models (TensorFlow/Keras). Experience includes developing SRGAN models to successfully upscale and enhance the resolution of satellite and aerial imagery. -Business Logic & Analytics: Creating smart data models and dashboards with complex underlying logic (e.g., inventory lifecycle tracking, predictive risk analysis) to drive actionable business decisions. My Approach: I believe in "Process & Forget" systems—building reliable, hands-off automation that runs silently in the background.

I work with US and international clients on GIS analysis, WebGIS development, location intelligence, remote sensing, and geospatial data engineering. My focus is on practical GIS systems: clean data, correct spatial logic, repeatable workflows, and outputs that teams can actually use. Recent US project work includes address matching and territory planning for operational teams, public facing GIS maps for policy and exhibition use in Omaha, property and building height analysis in Los Angeles, and a browser based weather graphics platform built with MapLibre, radar layers, timeline controls, and export ready map views. International work includes site selection analysis in Germany, parcel and location intelligence workflows, PostGIS and QGIS topology cleanup, UK air quality grid matching, raster processing, and WebGIS tools built with MapLibre, Google Maps API, AWS, and spatial databases. I can support projects involving GIS analysis, WebGIS dashboards, PostGIS workflows, raster and remote sensing analysis, automated geospatial pipelines, and custom mapping tools. If you need a one time analysis, a repeatable GIS workflow, or a full WebGIS prototype, I can take the project from raw data to final deliverable with a clear technical process.

I am a GIS Expert focused on spatial modeling and decision-support systems. My work goes beyond map production. I design structured geospatial workflows that transform complex spatial data into measurable, decision-ready outputs. My expertise includes multi-criteria suitability analysis, raster-based environmental modeling, hotspot detection, spatial aggregation, and risk assessment using ArcGIS Pro and QGIS. I work extensively with infrastructure and planning datasets, building analytical models that support strategic site selection, optimization, and data-driven decision processes. My approach emphasizes technical depth, clear methodology, and delivering reliable spatial intelligence that directly supports operational and strategic decisions. If your project requires advanced spatial thinking and robust GIS execution, I can provide structured, high-impact solutions.

I have 10+ years of experience on web app development(back end + front end) especially GIS projects Experienced; LeafletJS, Mapbox, Openlayers, Geoserver, PostGis, Google Map API C#, .Net Framework, Asp .Net WebForms, Asp .Net MVC, Asp .Net Core Angular+Openlayers Geoserver REST API
