I was a lead software architect on the Enterprise Trouble Management System (ETMS) project.• Perform design reviews and architectural direction on all non-trivial changes within ETMS.• Designed and built new High Availability features into ETMS to reduce the datacenter failover time from 90 minutes to 60 seconds.• Designed and built a JMS messaging server to deliver JMS messages via a REST interface. This infrastructure is currently delivering 20+ million/day to JMS and REST clients in our live Production environment.• Designed and built a business rules engine to drive automations.• Designed and built the ETMS automation system using BPMN processes; using jBPM as the core engine. A web-based UI is used to build a BMPN process that mirrors human workflow steps, the workflow engine will then perform these manual steps in an automated fashion. This engine is currently running 250,000+ processes/day, which has enabled our user community to automate a large part of their workflows.• Designed and built a filter language using ANTLR with an SQL-like syntax to filter a real-time stream of DTO objects. This filter engine is used to drive ETMS automations.• Led the team that rewrote the EJB interface implementation with a REST server implementation.• Defined and built the CM infrastructure to support moving the team to an agile development methodology using a Subversion/Maven/Hudson continuous integration environment.

• Worked as a senior engineer on the server team building services to drive the customer portal.• Designed and implemented REST services to support the new portal (using Jersey as the implementation provider). • Implemented several database backends using Hibernate and iBatis.

• Designed an implemented server side services• Wrote a customizable, annotation based, DTOMapper implementation that can convert between domain objects and DTOs. • Wrote an annotation processor to convert Java DTO classes into BlazeDS compatible ActionScript classes automatically during the build. • Modified Cobertura to ignore trivial (pulled this functionality from an existing patch) or generated methods. This allows us to focus on code written by developers in our coverage reports.

(2005-2010) Moved to the architecture team on the Enterprise Trouble Management System (ETMS) project within Verizon Business. • Lead developer on a small team that migrated ETMS from DB2 Mainframe to Oracle RAC. This was a very successful project that was noted across Verizon Business for the seamless transition.• Designed and implemented a performance monitoring application for the ETMS servers to monitor 1000s of monitoring points (gathering counts and response time) within 50 WebLogic instances across multiple hosts in redundant datacenters. It provides real-time notification when performance deviates from recorded trends. • Designed and built a custom-built workflow engine to drive the business logic flow. Each workflow step is a reusable class implementation. Also, implemented an Eclipse plugin to visually represent these workflows and linked to the class implementation to make it a seamless developer experience• Co-designer for the new ETMS architecture, as it was re-written from C++ to Java. This was a gradual conversion over 5 years to port 200,000+ lines of C++ to Java and not disrupt external interfaces or users.(2000-2004) A member of the IMPACT project within Verizon. Designed and implemented the AlarmHandling subsystem within IMPACT. • Designed and implemented a flexible “plug-in” Java server architecture to collect, correlate, process, and distribute alarms received from Network Monitoring Platforms from many different vendors. To support a new vendor, a new plug-in is implemented and alarms from this vendor can then flow into the system and be processed by all of the downstream automations• Designed and built a seamless failover mechanism. In the case of a failure in one datacenter, processing will seamlessly failover to the geographically redundant datacenter within 3 seconds.
