I have 26 years of experience as a software developer/engineer with a wide range of experience including client server applications and deployments, Java based web applications, database applications and various objects in Oracle, SQL Server, etc.  including deployment and configuration of all of the above.

For web applications, just use Java, Spring (MVC or Web Flow), JSP, javascript, jQuery, Spring JDBC and serve it up on Tomcat.  You choose the database.

I'm now getting into Business Intelligence and the burgeoning world of Data Science.
