I am a GIS Analyst and Full-Stack Developer with extensive experience in building high-performance map services, processing drone imagery, and developing complete web applications. My combined background in geospatial technologies and modern software development allows me to deliver end-to-end solutions, including data processing, map publishing, and fully functional web dashboards. I specialize in publishing and optimizing WMS, WMTS, WFS, and TMS map services, processing orthomosaics, DEMs, and DSMs using Agisoft and Pix4D, and building spatial databases with PostgreSQL and PostGIS. I work confidently with QGIS, ArcGIS Pro, GeoServer, Mapbox, and other industry-standard tools. I can clean, prepare, and analyze GIS datasets, create custom vector tiles and basemaps, and design scalable GIS pipelines. As a full-stack developer, I build complete web applications using Node.js, Express, React, TypeScript, and Next.js. I develop custom mapping dashboards, REST APIs, authentication systems, and admin panels. I also automate geoprocessing workflows and integrate GIS data into modern web platforms. My project experience includes national land-use map services, drone orthomosaic WMTS systems for mining, real-time GPS tracking dashboards, cadastral map services with parcel search, environmental monitoring platforms, and custom urban planning basemaps. Clients work with me because I combine GIS expertise with software engineering skills, allowing me to deliver complete solutions from raw data to production-ready applications. I focus on performance, accuracy, clear communication, and reliable delivery. If you need a specialist who can process GIS data, publish map services, and build robust web applications around geospatial systems, I can provide a professional and scalable solution tailored to your project.
