I have been working with Go since early 2017.  I have created two web solutions for customers with Go: RESTful web service for managing and viewing medical reports, and a gRPC web service that managed geojson files that were stored in Azure Blob Storage.

I have used Kotlin for implementing many web services and a few microservice architectures in the GIS space.  There is a fantastic ecosphere surrounding it and the JVM.

I have been involved with the Microsoft technology stack for more than 20 years, and have created hundreds of solutions for customers.  Recently, I have developed and deployed a dotnet core 2.1 backend that provides GIS mapping services to other applications.My expertise is more on the backend and Azure/Cloud services.
