PROFESSIONAL EXPERIENCE
NOKIA, Arlington Heights, IL February 2012 to October 2015
Senior Network and Security Engineer
Network and System Integration lead for the Small Cell Security and WiFi 802.11b/g/n/ac Performance projects, which provide end-to-end data encryption for secure communication, priority handling of voice and data calls, and access points management.
Implemented scalable network solution, which saved $75,000 in equipment footprint, by configuring dynamic routing protocols, GRE tunnels to connect four labs requiring 50+ Juniper and Cisco Nexus/3750/7600 series.
System integrated and configured 12 Juniper and 5 Cisco Routers/Switches, and Small Cell Access Points in order to perform end-to-end system TCP/IP, UDP, and IPSec test cases that contributed to $75,000+ in defect prevention.
Programmed Python using OOP concepts to interact with SQL in order to automate network connectivity diagnostics and to backup 50+ routers/switches configurations files, resulting in cost savings of $56,000.
Programmed Python, which allowed for 25% reduction in test cycle time, to parse TCP/IP and UDP IPSec traffic in order to summarize results for senior technical leadership.
Applied Agile methodology in system verification, measuring WiFi traffic throughput while injecting LTE traffic in adjacent frequencies; prevented $68,000+ in field deployment defects.
NOKIA SIEMENS NETWORKS/NOKIA, Arlington Heights, IL April 2011 to February 2012
Senior Software Engineer
Technical Lead for the Small Cell Debugging and Diagnostics team, which provides Windows PC applications for field engineers to troubleshoot access points.
Led 4 engineers, separated geographically, to produce embedded C/C++ code to perform diagnostics on access points; applied Agile and white box testing, which resulted in 50% software cycle time improvement over conventional waterfall model.
Prototyped PC applications requiring C/C++ code and utilized vendor code resulting in 75% reduction in code creation.
NOKIA SIEMENS NETWORKS, Arlington Heights, IL April 2007 to April 2011
Senior Network and QA Engineer
Test and Network Lead for the WiMAX program, which is a wireless technology providing broadband connections and cellular backhaul over great distances.

FLUOR DANIEL, Chicago, IL June 1993 to June 1996
Senior Software SQL Programmer
Technical Lead for the Environmental Emissions Program, which monitors emissions of Gas and Coal plants as per EPA regulations.
Led 3 Clipper-SQL database programmers in producing SQL applications to monitor emissions for 40 gas/coal plants.
Innovated data-driven Clipper-SQL code that reduced existing application lines of code by 50%.
