Erin Schnabel

I am proficient with Object Oriented principles, design, and analysis. I was the development lead for the WebSphere Application Server Liberty runtime from it's initial release through 8.5.5.6. I've developed web applications using Perl (both CGI and Fast-CGI), PHP, and Ruby/Ruby on Rails, and javascript front-ends using JAX-RS or Servlets for the server-side. I am familiar with JSPs and JSF, though I prefer the ease-of-use provided by JAX-RS.

I've worked in both the Core and Enterprise Expert Groups for the OSGi standards body, and have experience with the OSGi core specification and several of the services defined in the compendium.

I'm now a Distinguished Engineer at Red Hat, working on Java, Cloud Native, Microservices, Quarkus, and other emerging technologies.
