As a Principal Engineer III, I oversee the implementation of architectural designs and produce microservice system-level architecture for various applications. My responsibilities also include functioning as a technical lead for a team of 6, encompassing software developers and QA analysts. This involves designing and authoring alpha versions of code for new projects based on Minimum Viable Product (MVP) requirements, documenting design through various diagrams, and facilitating training sessions for the team on the new product. I take part in all stages of project planning and closely collaborate with Product Owners using Agile Scrum methodology to map out work for every program increment.Simultaneously, I participate in the development and design of multiple software projects connected to network automation services impacting millions of Charter mobile devices, DOCSIS devices, and routers. My experience extends to designing, developing, and deploying high-demand distributed microservice applications that accommodate over 4,000 transactions per second. Collaborating with my team, we tackle the unique challenges of designing software solutions capable of fulfilling substantial requirements using a variety of programming languages such as Python, Java, and Ruby. As an AWS Cloud Practitioner, I am presently working towards obtaining AWS Solutions Architect and AWS Developer certifications

As a Firewall Expert, my primary duties revolved around developing backend automation for virtual service deployment into OpenStack Private Cloud Infrastructure, employing tools such as Cisco NSO and OpenStack, as well as various virtual firewall devices (Fortigate and Palo Alto). I rigorously tested the security features of these devices, subsequently scoring their performance to qualify them for production use. Additionally, I generated test scenarios that have revealed vulnerabilities in the Firewall software, resulting in vital code hotfixes with vendors.In my role, I also tested all orchestration services to verify software services are compliant with the ETSI NFV MANO standards for Charter's NFV solution. I was accountable for VNF service development on the Cisco NSO platform, crafting comprehensive services that include automated deployment of virtual security virtual machines utilizing OpenStack NEDs. I closely collaborated with Cisco to develop the virtual security NEDs, ensuring the security features offered to customers are adequately supported through the configuration of NSO. I have demonstrated Charter's NFV solution at industry conferences and advocate for adopting a cloud-native architecture. My experience also encompasses deploying a high availability production NSO system into Charter's national network and actively working on the development of service code updates.

As a seasoned Network and Voice Specialist, I held expertise in the installation, configuration, and troubleshooting of customer setups involving FortiGate Firewall solutions. I proficiently pre-configured FortiGates with standard network monitoring and connectivity requirements and handled the installation and configuration of VPNs for site-to-site and remote connectivity using IPSEC or SSLVPN. I managed FortiGate license registration and installation and setup Firewall UTM scanning as per customer requests, which included AV, IPS, Web Filtering, and application filtering. I established Identity-Based policies using an Agent-Based FSSO solution and configured QoS shapers and policies on the FortiGate for traffic prioritization. Additionally, I adeptly configured failover between multiple ISP connections on the FortiGate and troubleshooted a wide range of firewall-related issues including network connectivity, VPN, content filtering, memory or CPU, PCI compliance vulnerabilities, QoS, and FSSO.In addition to my network expertise, I showcased skills in voice gateway installations and troubleshooting, specializing in ADTRAN systems. I carried out the installation and turn-up of ADTRAN voice gateways to terminate SIP or ISDN trunks to customer equipment, as well as the registration of SIP trunks to Broadsoft session border controllers. My responsibilities included setting up FXS ports on ADTRAN for call management, provisioning phone numbers, and verifying call routing and subscriber registration in Sonus SBC. I proficiently troubleshooted a multitude of issues related to SIP messaging, ISDN messaging, trunk provisioning, call quality, network connectivity for RTP flows, SS7 messaging, and upstream PSTN issues. Furthermore, I handled call routing and call feature issues in Metaswitch SBC and collected and analyzed packet captures to isolate and address degraded call quality or connectivity issues.

As an experienced Network Engineer, my primary responsibilities included assisting customers with network migrations from their previous service provider networks to the West IP MPLS. I played a vital role in network design and configuration to ensure a seamless customer experience. Frequently, I determined a new customer's network and application requirements, and recommending and configuring the network according to their custom needs. My work also encompassed the configuration of custom QoS policies required for customer application needs, both locally and in the cloud on the MPLS.In terms of network configuration and troubleshooting, I was proficient in handling multiple different customer networks, utilizing all routing protocols supported by Cisco products (RIP, EIGRP, OSPF, BGP) in an MPLS environment. I managed and resolved advanced routing issues on customer networks and configured and troubleshooted LAN and WAN redundancy over MPLS. I aided customers in configuring cloud firewalls hosted by West IP and handled MPLS routing and connectivity issues in a service provider network environment with hundreds of customer VRFs. I actively participated in resolving customer escalated network or voice outages and addressed remote client connectivity issues with IPSEC or SSL VPNs. Other aspects of my work involved allocating and routing public IP space owned by West IP to various customer devices to establish internet connectivity, troubleshooting QoS related issues, dealing with escalated circuit incidents with transport carriers, and analyzing packet captures to resolve complex routing or network-related issues.

As a proficient Network Engineer, my role involved providing key support to customers by implementing various FortiGate firewall changes and installing site-to-site IPSEC tunnels and SSL VPN functionality. I was responsible for creating new SSL VPN users and setting up various remote authentication methods such as LDAP, RADIUS, and two-factor authentication for VPN logins. A significant part of my role was assisting customers in installing identity-based firewall policies using Active Directory user groups sent to the firewall via the FSSO Collector, troubleshooting VPN and IPSEC tunnel connectivity issues, and configuring and troubleshooting failover for multi-homed customer routers. I was skilled in configuring policy-based routing for specific customer needs, manipulating routing tables using all types of routing protocols on customer equipment (OPSF, EIGRP, BGP), and isolating and locking down workstations involved in network attacks or abuse. In addition, I handled configuring campus LAN and WLAN connectivity across the MPLS, ensured the correct application of QoS, troubleshot QoS related issues with transport carriers, and worked with IP SLA for tracking reachability.My voice-related responsibilities encompassed troubleshooting voice quality issues related to circuit problems, QoS, or network connectivity issues. I adeptly utilized packet captures and network monitoring software, such as Wireshark, to verify phone signaling and call attributes in order to troubleshoot voice problems. Furthermore, my tasks involved creating new or editing existing TACACs users and network resources, assisting customers in planning disaster recovery scenarios related to network connectivity, and responding to change requests to DNS entries on our name servers. My comprehensive understanding of both network and voice-related issues ensured efficient problem resolution and optimal system performance
