• Experience with back end development using C#/.NET and JavaScript/TypeScript (Node.js, Next.js, Express).
• Solid understanding of API design, data integration, and system architecture.
• Experience with geospatial technologies such as ESRI, PostGIS, and Mapbox.
• Demonstrated ability to diagnose and solve complex technical problems.
• Strong communication and collaboration skills, with the ability to explain technical concepts clearly.
