PROFESSIONAL SUMMARY

  • 17+ years of experience as a network engineer specializing in RF wireless technologies and telecommunications (4G/LTE, 5G/NR, WiFi, CBRS) for lab and field testing in indoor/outdoor networks.

  • Orchestrated cross-functional teams of 30+ engineers across hardware, software, and testing to resolve critical RF performance bottlenecks, improving major KPIs by 40% and reducing customer complaints.

  • Patented software for Big Data and ML: Developed LTE PIM Catcher (Patent #10009784).

  • Drove operational efficiency by redesigning capacity breach thresholds through data-informed decision-making, increasing profit margins by 10%. Reduced unnecessary CapEx and optimized resource allocation, delivering measurable business value across multi-million-dollar network investments.

  • Led development of real-time Python/JavaScript automation tools, mentoring junior engineers on implementation. Managed a cross-functional initiative that streamlined diagnostics for 20+ field teams, reducing field revisits and costs by $100K annually.

  • Engineered a Linux-based 5G/LTE/WiFi test tool (iPerf/FTP) for indoor (P2P) and outdoor (GPS) testing, saving $15K per license. Collected metrics via SSH (Cradlepoint R1900) and throughput via curl/iperf (TCP-UDP). WiFi data parsed via nmcli/iwconfig.

  • Developed a cost-effective QGIS/PyQGIS mapping solution (indoor/outdoor reports), cutting license costs by $5K/user by qchainage/mmqgis modules.

  • Built Python regex parsers to accelerate file comparisons, boosting engineer productivity by 5–10% in daily tasks.

  • Developed a Python-based solution to convert Planet coverage prediction TIFF files into polygons, enabling free QGIS-based geo-filtering and analysis. Eliminated dependency on paid licenses, saving the company $5K/user in software costs.
