Software Consulting Services

Amazon Cloud Computing

I have extensive experience in the architecture and implementation of large scale web applications on the Amazon Web Services (AWS) Cloud. I can work with your organization to design AWS cloud based applications and move existing applications to the AWS Cloud. I have deployed large scale Java web applications that leverage a variety of AWS services. These include:

The nderground social network (www.nderground.net) was an example of how I have leveraged AWS services to build a large, scalable web application. nderground was a social network that was designed for privacy and security. nderground was live from 2015 to 2021.

When I built the nderground social network I used the Grails framework. After completing nderground, I have focused on full stack Java web application development using the Spring ecosystem (Spring Boot and Spring MVC).
