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:
Full stack Java web appliation development leveraging the Spring ecosystem.
AWS Elastic Beanstalk for scalable web applications support.
AWS Lambda for serverless computing support and increased application scaling.
RDS/Postgres and MySQL database design and deployment
NoSQL databases: DynamoDB, Neo4j, Elasticsearch, Solr and Redis
AWS Simple Email System configuration and deployment.
AWS Cognito for authentication
AWS Capacity Planning aimed at minimizing costs and maximizing scalability.
Cloud and Web Security
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.
Full stack web application development in the Java/Spring Ecosystem
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).

and Signal Processing. This is an extensive set of web pages on
wavelets, wavelet applications and the Fourier transform. A large
body of extensively documented Java and C++ source code implementing
wavelet, Fourier transform and statistical algorithms is published on
these web pages.
Container Class and Reference Counted Objects. This is a
set of C++ reference counted classes that supports a string class (this software
was developed before the C++ Standard Template library std::string class was mature).
ANTLR Parser Generator. This set of Web pages discusses why
the ANTLR parser generator should be used and provides a set of
examples showing how ANTLR grammars can be used to generate parsers.
These Web pages have been cited as references on the main ANTLR web site
