Need a GIS developer who can build the full solution — from database to map interface? I deliver production-ready geospatial applications for utilities, municipalities, and infrastructure teams using .NET, React, ArcGIS, Leaflet, and cloud infrastructure on AWS. With 100% Job Success on Upwork and 6+ years building GIS systems at POSM Software, I've shipped desktop, web, and data solutions used daily by field inspectors, analysts, and leadership — both online and offline. WHAT I BUILD Desktop GIS Applications (ArcGIS Runtime 200.x / .NET) WPF and WinUI apps with MVVM, offline maps (MMPK/TPK), feature editing, attachments, geodatabase sync, and MSI/MSIX packaging. Result: Office staff update assets without needing ArcGIS Pro licenses. Web Mapping Platforms (React / ArcGIS JS / TypeScript) Interactive maps with asset search, filters, custom popups, role-based access, and responsive UI using Next.js and Tailwind. Result: Crews find assets in seconds; leadership sees live operational status. Open-Source Mapping (Leaflet / GeoServer) Leaflet-based web maps served from GeoServer on AWS, with WMS/WFS layers and custom tile caching. Currently running a live Leaflet app for infrastructure visualization. Result: Cost-effective alternative to proprietary stacks for clients who need flexibility. Data Pipelines & Integrations SQL Server and PostGIS replication via CDC/AWS DMS, Python/ArcPy ETL with nightly syncs, validation rules, and alerts. Built a custom API connecting POSM Software directly to ArcGIS Online — no ArcGIS Enterprise needed. Result: Significant infrastructure cost savings. Cloud Infrastructure (AWS) Production GeoServer on EC2 with ALB, Auto Scaling, EFS, and multi-client spatial data hub architectures. Result: Scalable real-time spatial data serving across organizations. Dashboards & KPIs Chart.js dashboards with completion %, backlog tracking, risk analysis, drill-downs, and CSV/Excel exports for management reporting. HOW I WORK Fast discovery: I map users, layers, edit rules, and success metrics upfront. Early wins: First milestone delivers a working map, workflow, or KPI. Iterative delivery: Small, testable improvements with clean documentation and training. I work comfortably with distributed teams and deliver in English or Spanish.

Geospatial Data Engineer with 5+ years of experience building reliable spatial ETL pipelines, PostGIS databases, and API-driven Web GIS solutions. I help teams turn raw GIS data (shapefiles, GeoJSON, GeoPackage, CSV, imagery outputs) into clean, queryable, production-ready datasets and interactive maps. What I can deliver for your project: - Python ETL (GeoPandas, Pandas): validation, cleaning, deduplication, joins, reprojection, automation - PostGIS / PostgreSQL: schema design, spatial indexing, performance tuning, spatial SQL queries, data loading - Spatial APIs: build or integrate REST endpoints for geocoding, routing, boundaries, tiles, and spatial search - Web GIS: Mapbox maps (layers, styling, popups, filters), data services, and map-ready outputs - Reporting & dashboards: Power BI/Excel outputs when needed, backed by a solid database layer I’m practical, detail-oriented, and focused on smooth delivery: clear milestones, clean documentation, and maintainable code. If you share your data sources and end goal, I can propose an efficient pipeline design and start with a small proof-of-concept.
