Senior Network Engineer/Principal Network Engineer
Work with Project Teams to implement radio communication systems with primary focus of network design and installation. The core consists of Sun and Windows Servers for voice and data services plus Cisco routers, Cisco ASA Firewalls, and Ethernet switches. WAN solutions include Alcatel MPLS, DS1/DS3, Wimax 802.16 wireless, and 802.11 wireless links. I designed networks with QoS using Class Based Weighted Fair Queuing and Low Latency Queuing. Routing solutions implemented include static, Cisco's EIGRP, and OSPF. For verification purposes, I created acceptance testing plans and network diagrams for maintenance support. Installed upgrades for server operating systems as well as network device software. Performed upgrades for Harris applications on servers and site equipment with minimal downtime for customers. After building a lab in our Harrisburg facility, I verified Harris applications and configurations by performing acceptance tests and by providing packet captures and debugging information of application logs with software/hardware developers. I assisted the Commonwealth of PA in their WAN upgrade of DS3 Microwave backbone to a MPLS solution. As new projects come in I provide design review recommendations based on each customer's requirements. I have performed capacity planning on systems for bandwidth usage and radio voice requirements. During system installations, I have created network management domain maps for network operation centers. I have also added voice user and subscriber units in application databases and have monitored performance and accounting data for system operations.
