The company recently merged with 6-7 companies, viz., Cross Telecom, CimTel, Potawatomie, Bravado, MBO etc. The company also added the Ericsson new core network. My responsibility is to manage the combined network, for both core & access, finding synergy among multiple networks, cross train the resources from multiple networks, and making the operations more efficient. I report to the CTO of network of the company.Major accomplishments during my tenure here-- Established & enforced handling a Service Orders and Trouble Tickets within 15 minutes of opening the ticket by the Service & Support Group (SSG), Customer Service Group (CSR) and Operations of the group of companies, while the technicians are at the customer premises.- Cross train RAN Technicians (for Access Network) and Core Technicians (for Core network) to better use the resource hours.- Merged several teams from 5-6 different company resources and unified them to a single work culture- Optimized Access Network by updating Azimuths and Tilts of many of the 120 cell sites at different locations to better cover our customers.- Turned on and managed IMS network for the Bravado Wireless. Migrated customers from Verizon Core to our own IMS Core.- Created the “Escalation Ticket Platform” for any of the teams to escalate issues.- Defined and maintained troubleshooting process and the time to resolve for escalation tickets.- Trained the Customer Service & Support Group (SSG) for better manage the customer tickets, reducing the number of ongoing tickets from 200 to 60.- Negotiating the upgrades and replacement of Microwave for better connectivity.

Designing & building a RAN & 5G Core lab for aviation. Measuring SINR, Signal Power level using Spectrum Analyzer, impact of weather & Doppler Effect on both air to ground and ground to air coverages. AURA Network Systems was recently awarded with the 450 MHz frequency range by FAA to serve the unmanned flying vehicles. This is the first network of this kind to create highly reliable 5G coverage. The network elements consist of Cisco ISR-4351, NCS-540 & NCS-5500 series routers. It also uses GIRD & Ondas radio elements for GRS & ARS.

Building C-Spire network using NSP (Nokia Service Platform): Working as a Senior Network Engineer to build & monitor customer containers accounts using the latest NSP platform, and test (as per RFC 2544) with EXFO. It includes the installation of new network elements Nokia 7705 & 7250, discover the customer, and adding the instances to the customer containers.

Working as a Senior Network Engineer for Nokia (previously ALU) production configuration, integration & troubleshooting. I support Verizon for their LTE Core (SR-1, SR-12, IXR-e etc.), eNSE Leaf & Spine infrastructure, VNF & SDN and 5G-NR interfaces through design, integration, testing & troubleshooting etc., E2E performance testing & validation, writing config files and MOPs, executing those as an operations engineer for Nokia (ALU).

Leading triaging Google Fi platform from telephony perspective, which includes IMS call flow analysis, Switching between carrier analysis etc. Google Fi is a MVNO providing wireless services to a wide range of wireless devices, such as Pixel, iPhone, many Samsung & Motorola devices. This platform switches between subscription profiles, with pSIM & eSIMs via different carrier networks, to get the best service & connectivity for the device. My responsibility is to analyze the bugs, find root causes & solutions. Since Google Fi is a relatively new platform, often we need to be innovative to find the patterns and best solutions through the process. The Fi platform interacts with the 5G core of T-Mobile (including Sprint now) and US Cellular networks, where triaging involves the flow through 5G Core elements AMF, SMF, UPF, NEF etc. Google Fi started supporting 5G NR platform with and without the support of LTE platform Core & RAN elements, following different 5G-LTE-3G combination strategies, including different backhaul strategies to support WiFi network use cases. Fi also supports 5G-NR services, such as Slicing, mMIMO, mMTC, uRLLC etc., as well as ZigBee supported devices & connections, in order to ensure low coverage with low battery power use cases in WPAN network. As a Tech Lead, my responsibility is to triage issues from internal QA team & customers, through an in-depth analysis, involving different 5G usages, and proposing changes needed to the development team.

This is an internet infrastructure development and installation company, serving 700+ local SMBs from Kansas City & vicinity, primarily responsible for running Ethernet (CAT5e, CAT6, CAT6a), Fiber & Coax Cable, and Installing network elements, such as Switch, Router, WiFi Access Point, Air Fiber (private wireless/WLAN, e.g., WiFi) connection between buildings, Surveillance Camera, Alarm System, Access Control etc. I bought this company in 2017 Feb as a side business, and grew the revenue year by year from $60K in 2017, to $123K in 2018, to $326K in 2019, to around $335K in 2020, when we changed the strategy to run the company as a profit based business entity, from a growth based one.
