I have 33 years of increasing responsibility and expertise in the planning, development, design, analysis, implementation, and administration of information systems utilizing database and Client/Server applications involving Oracle, SQL Server, UNIX, Java, JSP, and scripting applications. His experience includes the design of applications for a variety of complex systems supporting commerce, telecom, health, scientific, and business applications with Java (J2EE, Core), Oracle, Apache, Weblogic Server on AWS, WebSphere, Spring Boot in a Lookup application to incorporate Docker.

I’ve developed and built Java packages in the Business Logic, Service, and Domain layers implementing complex SQL database search and update using JPA, Hibernate, and Spring-JDBC. I’ve also have developed complex Oracle PLSQL stored procedures and packages for batch and web applications.

My server-side development experience includes extensive Shell Scripting on many Linux and Unix Servers that included embedded SQL and my own Shell, Perl, C/C++ applications. I’ve also created PHP-MySQL web applications supporting DOJ, and Perl and Python Linux/Unix server applications supporting data and file manipulation and a Python web crawler.

Recent health care contract experience included supporting registration application that utilized JQuery and Bootstrap/CSS which integrated Ajax controls. This was utilized by the enterprise Java web application I was enhancing for patient registering for tests, diagnosis, and studies.

WEB SERVICES

He’s developed code utilizing mostly Rest Http APIs and WebSockets for web and standalone applications. Applications I've bug-fixed or enhanced utilized JMS (Java Messaging Service), Spring Security, Spring Web Services. He has beginner-level experience with JQuery and Bootstrap/CSS and worked with JavaScript and HTML5 on all of my recent enterprise web development projects.

I have used JUnit recently for unit testing business logic code and recording test coverage. Used Artifactory, Subversion in web development supporting USPS and NCI on recent projects.

Application Servers utilized by applications I developed or fixed included Weblogic in AWS Cloud, Websphere, JBoss, Tomcat, with build tools Ant plug-in and Maven command-line.

All recent contracts and projects utilized Agile Scrum methodology.
