- Expanded and optimised the metro-fiber core, integrating 400 Gbps Cisco/Juniper platforms and diverse rings to keep latency below 5 ms and Internet uptime at 99.99 % for 1,000+ business circuits.
- Delivered turnkey DIA activations by carving customer-specific VLANs, assigning /29 IPv4 and /56 IPv6 blocks, and auto-generating configs via Ansible + NetBox/Nautobot—cutting install lead-time by 40 %.
- Established and fine-tuned BGP peering with upstream carriers, IXPs and cloud on-ramps; applied prefix filtering and Flowspec/RTBH to harden the edge against large-scale DDoS attacks.
- Implemented and supported a hosted-VoIP/SBC stack (Kamailio/BroadWorks), building LLQ/DSCP QoS, E-911, IVR, and robocall filtering while sustaining ≥4.3 MOS across 10 M+ calls per month.
- Designed a leaf-spine fabric and active-active firewall clusters for the Sunday Drive data-centre, handing off secure VLANs to colocation racks and private-cloud pods.
- Administered Palo Alto/Fortinet NGFWs and Duo-integrated NAC, drafting micro-segmentation ACLs and driving quarterly firmware upgrades that closed every critical CVE.
- Built Grafana/Prometheus and NetFlow observability dashboards, forecasted utilisation, and triggered fibre/optics augments before links hit 70 % to prevent congestion.
- Automated nightly config backups and led semi-annual DR drills, proving full core restoration in under 30 minutes and meeting all RTO/RPO objectives.
- Served as Tier-III escalation and on-site cutover lead for new campuses, resolving BGP/OSPF and VoIP QoS issues with 2 h MTTR and maintaining 95 % CSAT.
- Authored gold-build templates, MOPs/SOPs and network diagrams, embedding best practices and reducing new-hire ramp-up time by 30 %.

Pyramid IT Solutions PVT LTD
05.2021 - 12.2022
- Deployed and optimized multi-site Cisco infrastructures, including 3600/3900 routers and 3550, 3560/3560-E, 3750, 6500 switches—delivering secure VLAN segmentation, OSPF/BGP routing, and IPsec VPN services.
- Rolled out Cisco ACS (RADIUS/TACACS+) for wired & wireless 802.1X authentication, integrating certificate-based access and MAC Authentication Bypass (MAB) for 100 % of corporate assets.
- Led firewall capacity planning, right-sizing platforms to support > X % traffic growth while maintaining sub-1 ms latency targets.
- Orchestrated quarterly firewall patching and firmware upgrades, eliminating critical CVEs and raising security posture to industry compliance standards.
- Engineered granular firewall policies—micro-segmenting DMZ, user, and server zones—to reduce lateral-movement risk and improve traffic visibility.
- Authored and maintained network-security SOPs and “gold-build” configurations, standardizing best practices across operations teams.
- Safeguarded business continuity by automating nightly firewall backups and validating restore procedures as part of the DR playbook.
- Delivered end-to-end WAN roll-outs for new campuses: provisioning last-mile circuits, configuring edge routers/switches, and establishing proactive monitoring dashboards.
- Resolved Tier-III WAN/LAN tickets—tuning BGP, OSPF, and EIGRP metrics.
