I am a senior GIS and geospatial technology consultant with strong expertise in designing, implementing, and optimizing enterprise GIS solutions for complex operational environments. My background spans ArcGIS Enterprise, ArcGIS Server, Portal for ArcGIS, ArcGIS GeoEvent Server, ArcGIS Pro, Python/ArcPy automation, raster data management, web GIS application development, and AWS-based deployments. I specialize in building scalable geospatial systems that improve decision-making, streamline workflows, and deliver measurable value for organizations that depend on accurate, high-performance spatial data solutions. Over the course of my career, I have led GIS architecture and development initiatives involving enterprise platform administration, automated ETL workflows, geodatabase design and maintenance, web service publishing, field data collection solutions, dashboard development, and real-time tracking applications. I have built and supported solutions using ArcGIS Field Maps, ArcGIS Dashboards, Experience Builder, Web AppBuilder, and ArcGIS Pro to help clients manage data more efficiently and transform it into actionable intelligence. My work also includes integrating ESRI technology with external systems and APIs, developing custom GIS applications with .NET, and supporting cloud-hosted raster and imagery management environments. I bring a combination of deep technical capability and practical business understanding, allowing me to deliver GIS solutions that are both technically sound and aligned with client goals. Whether the need is ArcGIS Enterprise administration, ArcGIS Pro map and data workflows, GIS automation, spatial data migration, dashboard creation, application development, or overall GIS modernization, I focus on delivering clean, dependable, and results-driven solutions. My experience includes configuring and administering enterprise GIS environments from the ground up, including server setup, portal configuration, service management, user access support, and performance optimization. I understand how to build GIS systems that are stable, secure, and ready for real-world operational use.

Production platforms that field teams use daily, executives present in meetings, and subscribers rely on. I build custom operational software for organizations whose work has outgrown spreadsheets, paper, email and software that almost fits. Dispatch and scheduling, work orders, inspections and compliance, asset and equipment tracking, and the management reporting that has to stay in sync with all of it. A lot of that work is geospatial. I work in ArcGIS Online and the Esri ecosystem, Survey123 and Field Maps, hosted feature layers and view layers, and custom web maps for internal and public use. When field data, maps and dashboards disagree with each other, that is usually a structural problem, and it is fixable. I also take on application rescue. If you have a project built in Lovable, Claude or another AI tool that demos beautifully and keeps breaking in production, my first move is finding out what is actually broken before building anything new on top of it. Supabase and Postgres, row level security, Vercel deployments, Stripe subscriptions and webhooks. Work I have built was featured at the Esri Federal GIS Conference Plenary, and activated during the 2021 Midwest Tornado Outbreak and Hurricane Helene. Core skills: custom operational software, dispatch and scheduling, work order and field service systems, inspections and compliance workflows, ArcGIS Online and Esri, Survey123 and Field Maps, executive and operational dashboards, React and TypeScript, Supabase and Postgres, row level security, edge functions, Vercel, Stripe subscriptions and webhooks, mobile and offline field apps, Python and SQL, data pipelines, API integration, document and PDF automation. If you have a spreadsheet that should be an app, a GIS org that needs to be rebuilt properly, or a platform that needs to go from zero to live, I can take it from architecture through deployment. And would love to.
