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.

Hi, I'm a senior engineer. I spent many years building software in Korea, and I recently came to Upwork to work with more great clients around the world. I can partner with you across the whole journey, from the first planning stage to launch. Years of building products, and of working closely with clients, taught me that the best results don't start with technical jargon. They start with listening. I take time to understand what you really want, agree on a clear scope and milestones with you, and stay with it to the finish. I've worked across a wide range of domains: full-stack web apps and SaaS, GIS and mapping platforms, real-time data and trading dashboards, legal and document AI, IoT and data pipelines, and business automation. My core stack is Python, Node, and React/Next.js with Supabase/Postgres, and I add AI (RAG, chatbots, LLM and agent integrations) wherever it genuinely makes the product better. What clients value most: I take your brief and turn it straight into a working PoC, so you can use and test it before you decide. I also bring ideas of my own into it, so you end up with something you can grow a real business on, not just what was asked for. Because I work fast, I usually prefer fixed-price projects, though I'm always happy to stay flexible when it makes sense. I'd love to meet you and get started. Thank you for reading.
