Lead design/engineer for the Clypsy app available on both the Apple App Store and the Google Play Store (See link below). This app was built and accepted to both app stores in less than 10 months and already has a good following. Responsible for the conception, design and implementation of the core EagleIQ Application Server. This is a robust, scalable platform that enables Solvepoint's clients to execute Progress 4GL business logic from the Java space as well as execute Java from a native 4GL API. The server is a fully multi-threaded, highly scalable Java application utilizing Java sockets and an optimized protocol. It includes capabilities such as enterprise level production monitoring at the event level, robust load balancing and many other high end features. It is being utilized by large organizations for high transaction count applications (such as Iron Mountain, McKesson, and more). A number of client API's have been built including Java, Progress 4GL, .NET and EcmaScript/JQuery over Java Servlet via AJAX/JSON.
Lead developer on a large enterprise application integration (EAI) Java based project for Bellsouth BTSI. Message Broker Databus for FCC319 for Bellsouth (BTSI)
Powertel Loyalty Administration Intranet Application Responsible for designing and building this system entirely in Java under the BEA Weblogic server. Built using Servlets, JSP on the server side (accessing an Oracle database) and used DHTML/JavaScript for the front end.
Lead a team that envisioned, prototyped and built an implementation neutral business transaction processing backend. This provided the ability to access Progress 4GL logic from any front-end capable of TCP/IP communication such as Java, C++ or Visual Basic. Responsible for building the first front-end to this architecture. It was a Java Applet based transaction processing system accessing over 40 business API’s written in Progress 4GL. These same business API’s were accessed using Visual Basic and C++. Part of a team of 10 to implement an Undo/Redo architecture to be used with systems requiring the ability to remove/insert financial events from/into history. This project necessitated designing a standard error recovery mechanism to be used throughout the system. John built this sub-system using a persistent object oriented design. He was responsible for documenting and training for this sub-system as well.
Lead architect and developer responsible for building and supporting the development architecture for all systems created by the division. This consisted of creating an Integrated Development Environment which is used not only by Fiserv developers but also by the end user (known as Power Tools). The IDE is highly object oriented with all application logic developed at the field and table level. This architecture allows the end user to add custom tables to the database while maintaining system integrity across product versions (written entirely in Progress 4GL).
