Key Achievements: Successfully diagnosed the root cause of a global Wi-Fi outage using Wireshark, highly contribited to the resolution in record time while sharing my troubleshooting process live with LSEG executives via screen sharing. Resolved Layer 1 to Layer 7 network issues affecting applications, Wi-Fi, CCTV systems, security doors, and AV devices at newly deployed sites. Rapidly resolved regional Wi-Fi outages and Data Center applications incidents. Diagnosed and fixed a wide variety of software bugs and hardware-related issues. Handled TACACS+ and complex NAC incidents with in-depth analysis and corrective actions. Solved advanced routing incidents by reviewing full-site configurations (OSPF, BGP, EIGRP) and working with ISPs to ensure proper route advertisement. Resolved QoS issues and INC's at CE, PE, and LAN/WAN levels Troubleshoted and resolved DMVPN failures and performance degradations across multiple sites. Restored internet connectivity across multiple sites by solving underlying Layer 3 issues Performed deep log analysis across WLAN, LAN, and WAN environments to uncover root causes. Maintained high efficiency in incident resolution, managing 25+ tickets per day during periods without critical escalations or critical complex incidents. Built LLD and HLD diagrams and designed Client-Approved Change Requests to remediate high-impact issues both as emergency and standard. Participated in on-call sessions with LSEG executives, guiding real-time resolution efforts with live troubleshooting walkthroughs. Contributed to the service takeover and transition of LSEG network operations. Diagnosed issues in CCTV systems, Polycom devices, video conferencing rooms, and business applications. Used Wireshark and traffic flow analysis to pinpoint bottlenecks and failures at all layers. Maintained excellent client relationships, combining technical precision with a professional and human-centered communication style in all interactions.

Network Technician L1 for BT Group | British Telecom Group, service provided to Santander Bank | Banco Santander. Key Achievements: • Provided 24x7 L1 NOC support for enterprise banking sites, owning initial triage, impact assessment and safe restoration actions for WAN/LAN incidents. • Managed tickets under ITIL (Incident/Problem/Change), meeting SLA/OLA targets through accurate prioritization, timely escalations to L2/L3, and clear customer-ready updates. • Troubleshot reachability and performance issues (packet loss, high latency/jitter, link flaps, intermittent drops) by correlating alarms with syslogs, interface counters, routing tables and end-to-end probes. • Validated MPLS circuits and coordinated with carriers: opened/managed provider cases, requested tests and field dispatch, captured evidence packs (timestamps, traces, counters) and chased RFO/RCA deliverables. • Performed SD-WAN health checks across underlay/overlay (transport state, tunnel reachability, path quality, route convergence) to isolate provider vs. overlay faults. • Monitored DMVPN/IPsec tunnels (tunnel status, hub reachability, basic ISAKMP/IPsec indicators) to distinguish transport problems from crypto negotiation issues before escalation. • Used monitoring/log platforms (e.g., SevOne, NGSD, ) to correlate alerts with device events, reducing false positives and accelerating fault isolation. • Attended clients calls to treat urgent incidents using Genesys (Call Manager), GENBAND • Treated 15 incidents per day • Supported segmented banking networks (VRFs/VLANs) and validated access-path impacts for critical services (voice, VDI, branch apps) during incidents and changes. • MultiProvider Ticketing and Reporting, Scheduled Work Execution, Service Adaptation, KCI and SLA Compliance, Scheduling, Incident Opening, Updates, and Closure, CHG Implementation, Configuration Change Documentation, Recurrent Alarm Monitoring, Runbooks Management, Dashboard Management, Router, Switch, and AP Maintenance.
