GIS analysts spend hours every day performing repetitive manual editing, topology validation, map book export, and attribute entry inside ArcGIS Pro.
ArcGIS Pro Add-Ins, ArcPy Workflows & Enterprise Esri Engineering
Custom ArcGIS Pro Add-Ins, ArcPy Geoprocessing Workflows & Enterprise Esri Development
We engineer custom ArcGIS Pro Add-Ins (.NET / C# & WPF), automated ArcPy geoprocessing toolboxes, custom ArcGIS Experience Builder & Maps SDK for JavaScript widgets, and hybrid Esri + PostGIS enterprise integrations.
// The buying trigger
You probably need this when…
Fragile ModelBuilder chains and unmaintained legacy ArcMap / ArcObjects scripts break during ArcGIS Pro upgrades or stall on large enterprise datasets.
Out-of-the-box ArcGIS Experience Builder and Web AppBuilder widgets lack the custom business logic, specialized UX, or external ERP/asset integrations your operations require.
Data is trapped in siloed File Geodatabases or slow enterprise services with no automated synchronization to cloud data lakes, PostGIS, or executive web portals.
// Concrete scope
What the engagement delivers
Every item is tied to an acceptance owner and evidence. Final scope is confirmed after data, security, and integration review.
Custom ArcGIS Pro Add-Ins (.esriAddinX) built in C# / .NET and WPF (MVVM) with custom ribbon tabs, interactive dockpanes, construction tools, and map tool overlays
Production-grade Python Toolboxes (.pyt), standalone ArcPy automation services, and ArcGIS API for Python scripts for unattended batch geoprocessing and Portal administration
Custom ArcGIS Experience Builder (React / TypeScript / Jimu) widgets and bespoke 2D/3D web applications using the ArcGIS Maps SDK for JavaScript
Enterprise Geodatabase (SDE) attribute rules (Arcade), branch versioning workflows, Utility Network validation rules, and automated QA/QC pipelines
Hybrid Esri-to-PostGIS / Cloud synchronization pipelines connecting ArcGIS Pro desktop editors to high-speed cloud databases and modern web dashboards
Signed deployment packages, installer pipelines, user training guides, and complete source code and deployment handover
// Delivery process
From evidence to operational handover
- 01
Workflow & Bottleneck Audit
Shadow your GIS analysts' current click-by-click workflows in ArcGIS Pro, inspect existing ModelBuilder/ArcPy scripts, and define the target UX and automation specs.
- 02
Add-In & Toolbox Architecture
Design thread-safe QueuedTask operations in the ArcGIS Pro .NET SDK, structured .pyt parameter validation, and clean REST/database integration contracts.
- 03
Iterative Sprint Delivery
Ship testable .esriAddinX builds, Python toolboxes, or Experience Builder widgets every two weeks for hands-on validation by your GIS team.
- 04
Enterprise Rollout & Handover
Package signed add-ins for centralized IT deployment, deliver full C#/Python/TypeScript source repositories, and train your internal GIS administrators.
// Proof before promises
How value is verified
No vanity accuracy number. Evidence is chosen around the operational decision and agreed before delivery starts.
- ✓Thread-safe ArcGIS Pro SDK (.NET 8 / C#) add-in architecture utilizing QueuedTask.Run to prevent UI freezing during heavy geometry and geodatabase edits
- ✓Automated ArcPy & GDAL hybrid pipelines that turn multi-hour manual QA/QC, parcel splitting, and layout export tasks into one-click operations
- ✓Seamless hybrid architectures bridging Esri ArcGIS Pro desktop editing with cloud-native PostGIS, DuckDB, and modern Next.js web portals
// Buyer questions
Frequently asked questions
What types of custom ArcGIS Pro Add-Ins can you build?+
Using the ArcGIS Pro SDK for Microsoft .NET (C# and WPF/MVVM), we build custom ribbon buttons, interactive multi-tab dockpanes, custom map and sketch construction tools, automated topology and attribute QA/QC inspectors, custom geodatabase connectors, and one-click cartographic PDF/report generators.
Can you migrate our legacy ArcMap Add-Ins (VBA / ArcObjects) or ModelBuilder models to ArcGIS Pro?+
Yes. With ArcMap retired, we regularly modernize legacy ArcObjects (.NET/COM) add-ins and complex ModelBuilder chains into modern, asynchronous ArcGIS Pro 3.x .NET SDK add-ins and maintainable Python Toolboxes (.pyt).
Do you build custom widgets for ArcGIS Experience Builder and ArcGIS Enterprise?+
Yes. We develop custom React and TypeScript widgets for ArcGIS Experience Builder (Developer Edition) as well as standalone web applications using the ArcGIS Maps SDK for JavaScript, integrating directly with your ArcGIS Enterprise Portal, FeatureServers, and external business APIs.
Can you connect our ArcGIS environment with open-source PostGIS or custom web applications?+
Absolutely. One of our core specialties is hybrid geospatial architecture—allowing your GIS specialists to continue using ArcGIS Pro and custom add-ins for desktop editing while automatically syncing data to PostGIS, GeoParquet, and 60 FPS web portals for unlimited organization-wide access.
