Team Lead, Mitigation SystemDirected and mentored a small team of developers to deliver important application functionality required by network operations users. Empowered the team members to play an active role in solution analysis and design.* Designed and developed web-token based security service for authentication and authorization with restricted back-end services.* Designed architecture integrating user developed scripts with the mitigation service using version control and automated deployment.* Provided primary production support of a cloud-deployed application architecture involving 17 virtual machines, and over a dozen micro services.* Consistently assisted and guided junior team members in up-skilling and taking increased responsibility, enabling them to transition to higher skilled positions.

Technical Lead, Mitigation SystemModernization of the legacy mitigation application from a non-highly available monolithic java service to a modern cloud based architecture.* Created a high level decomposition and design of monolithic application functionality facilitating implementation by a small team of developers.* Identified and separated monolithic service functionality into separate areas of responsibility that were developed as separately modifiable, maintainable, deployable, and scalable services, greatly improving the robustness of the system.* Expanded cloud based micro service architecture to function across multiple data center regions, transparently handling the loss of an entire region with zero downtime.* Reduced production deployment time from hours to several minutes by using Ansible playbooks and python wrapper scripts that provide a turnkey deployment solution.* Significantly improved the capability of network operations users to diagnose and mitigate network problems by giving them the ability to write scripts in a modern scripting language, greatly advancing the degree of automation capable through interaction with network devices.* Enabled security and horizontal scalability by redesigning and converting a legacy CORBA client API into a fully RESTful HTTP based interface.

Lead Developer, Mitigation SystemMaintain, enhance, and support a system that is used by operations centers for network device connectivity and interrogation, data collection, and configuration.* Considerably expanded the footprint of network devices connectable by the system by integrating the Verizon telecom network devices, and building in access to new network technologies.* Improved the quality of the existing code, and increased its maintainability by integrating test driven development (TDD) for new code, and retrofitting TDD to major application components, allowing for safe refactoring.* Reduced the legacy codebase size by 10-15% through refactoring.* Directly engaged with users and network security to establish access mechanisms and authorization for system connectivity to network devices.

Lead Developer, Correlation SystemDesign and implement a system for correlating circuits that are affected by an outage with the network alarms related to the outage.* Guided a team in implementing a JBoss/JavaEE hosted application that collects data correlating circuits affected by a network outage with alarms generated by the outage.* Interfaced with multiple systems to collect and store circuit to device alarm relationships.* Facilitated root cause analysis of outage events by generating reports of device alarms and affected circuits.* Enabled downstream systems to correlate proactively generated trouble tickets with tickets created in response to customer trouble notifications.

Developer, Topology System* Developed service to provide clients with network topology information collected from multiple disparate sources enabling network elements and alarms to be associated with customer, location, and device information.* Increased service performance dramatically by developing a hierarchical cache that was able to be updated and aged at a high level of granularity.* Recognized as one of MCIs “100 Heroes” for system consolidation efforts that reduced disk storage payments by 70%

* Designed and implemented a custom electronic mail system that serves over 20,000 users.* Implemented and maintain several web servers used by nearly 200 commercial web sites, and over 6,000 personal web pages.* Built an in-house trouble ticketing system that provided tracking, assignment, and prioritization of system and user administrative functions.* Worked with internet and intranet routing and network topology.* Performed system administration functions for several unix servers and a network of over a dozen PCs.

* Manage 35 IBM RS/6000 workstations used for mission critical operations and in-house development.* Provided system security, training, installation and configuration of operating system software, network connectivity, and troubleshooting of both hardware and software problems.* Coordinate with internal and external agencies for installation of applications software and performance monitoring* Provide direct support to operations for applications problems

* Developed and maintained ground system software for the Global Positioning System (GPS) network.* Organized the requirements screening panel, and tracked all software change requests
