Develop and maintain Java agents for IBM’s Application Performance Management (APM V8) on-premise and SaaS offerings. Development includes writing the Java code to collect performance metrics from the target system and designing the UI component layout rendered by the APM UI. Agents are built using IBM’s Agent Factory, Blue Medora’s proprietary Ex Uno library, and a combination of Rake, Gradle and ANT build scripts. Development environment is Java 1.8 and IntelliJ IDEA on MAC OS with GitHub for source control. Agents were required to run and be tested on Windows server, Red Hat and SUSE Linux, and AIX. Developing the agents required quickly becoming familiar with each monitored system.● Amazon EC2 Agent: Uses AWS SDK for EC2 and CloudWatch to collect KPI metrics. Developed the APM agent and a new custom data provider using Ex Uno.● Red Hat JBoss EAP 6/7, Wildfly 8-10 Agent: Uses JMX to collect KPI metrics. Developed the APM agent and a new custom data provider using Ex Uno.● Oracle WebLogic 12 Agent: Uses JMX to collect KPI metrics. Developed the APM agent and a new custom data provider using Ex Uno. ● Microsoft Azure Compute Agent: Uses Azure REST API’s to collect KPI metrics. Developed the APM agent using an existing Ex Uno data custom data provider.● Gradle build migration: Participated in the migration of Rake and ANT build scripts to Gradle. ● IBM Agent Configuration: Developed APM UI plugin for configuring the JBoss and WebLogic agents. Written in JavaScript using Dojo toolkit.● APM Deep Dive and Transaction Tracking: Extended the JBoss and WebLogic agents to report enhanced application diagnostic information. Uses custom toolkit provided by IBM to instrument application classes.● JEE Test Applications: Developed JEE test applications that were used to put a load on the WebLogic and JBoss servers. These applications allowed us to generate and verify KPI metrics for Servlets, JDBC connection pools, EJBs, SOAP Web Services and JMS queuing.

Senior developer and Fujitsu Transaction Services. • Maintain and enhance GlobalSTORE application using knowledge of VB.NET, C#, C++, WPF, WCF. • Create functional requirements, high level design and detailed design for new GlobalSTORE features and bug fixes. • Create data export tool using C# and TSQL that can mine daily sales transaction data from the GlobalSTORE database and export the data in the flat file format required by a legacy head office data warehousing tool. • Analyze and fix poorly performing GlobalSTORE Back Office Reports. Rewrite TSQL stored procedures where needed. • Design set of MS Windows services that import and export of data between a legacy third party head office application and GlobalSTORE. The export requires mapping GlobalSTORE data to a flat file format and then using a legacy DDE channel to notify the third party that the data was available to be picked up. • Implement an automated POS regression/stress test tool in VB.NET using WCF and Fitnesse.

Senior member of the ISIS V5 development team. ISIS V5 is a .NET Point of Sale system that includes an MS Windows POS terminal application written in C++ and C# and a back-office application implemented as a Web application written with ASP.NET 2.0 and C#. • Design and implement a task scheduler as multi-threaded Microsoft Windows service written in C# using the .Net Framework 2.0. The task scheduler can dynamically load and invoke scheduled tasks at runtime using .Net reflection. • Develop a management console for the scheduler in C# using Windows Forms. • Develop a client/server interface between the management console and the Windows Service using .Net Remoting. • Re-architect the core ISIS V5 application to remove the extensive use of singleton objects. This was done to make it possible to write unit tests without having to initialize the entire application. • Design and implement the Web Service used to integrate the front-end application with the back-office application. One key requirement of the web service is to parse the IXRetail POSLogs generated by the front-end and load the parsed data into the back-office data repository. • Design and implement the tax calculator service used by the POS front-end to calculate taxes. • Create automated build system for the back-office application using NAnt and CruiseControl.NET. • Develop the ISIS TaskScheduler task used to provide database maintenance. • Develop the back-office application code that sends POSLog XML documents to a web service on an enterprise host server. • Develop web service on the enterprise host server that processes POSLog XML documents and updates customer loyalty information such as points earned and redeemed. • Develop code to export POSLog XML documents from the back-office database and archive the exported documents in zip files.

POS Sales Pluging: Develop an custom RCSwitch plug-in action to extract POS sales information from an XML document and import the data into an MS SQL database. • Designed and implemented Java classes that use XPath and XSLT to extract and manipulate the XML data in preparation for insertion into the database. • Designed and implemented Java classes that use JDBC to import the extracted data into the MS SQL 2000 database. ARTS KPI Sales Analysis: Member of a two person team that created a Java based Sales Analysis tool for reporting sales data and key performance indicators (KPI) mined from a database that conforms to the ARTS data model. • Converted two legacy applications to run as RCJSwitch plug-ins. Refactored both plug-ins to make them testable, added JUnit tests, and then extended them to meet new requirement. One plug-in parses IBM 4690 SA and GSA transaction log files and outputs an ARTS IXRetail POSLog XML document. The second plug-in parses the ARTS IXRetail POSLog XML document and inserts the transaction data into an ARTS standard database. • Used JPerfAnal to analyze performance bottlenecks and redesigned one plug-in, providing a 400% speed improvement. The tool can now import around 9 POS transactions per second on server class hardware. • Created installation utility using NullSoft software and ANT. The installation script allows the application be installed to run from the command line or as a Windows Service. • Introduced QA to the Fitnesse Acceptance Testing Framework. Wrote custom FIT fixtures used by QA to write test to verify that the POS transaction data is correctly imported into the database.
