India

Message

At Landis+Gyr, I manage and support GCP networking for a global IoT platform, including VPCs, Cloud Router, Cloud NAT and firewall rules. I review and deploy Terraform configurations, and design and troubleshoot secure IPsec VPN connectivity between data centers and GCP.

I drive change implementation, incident resolution and root cause analysis to sustain high availability and meet SLA targets. By collaborating with cloud, security and infrastructure teams, I helped achieve 99.9% uptime for the platform.

Earlier, at HCLTech, I led a LAN transition for Tenneco International with zero critical downtime and delivered a legacy-to-SD-WAN transformation for WestRock using Cisco Viptela. My experience also includes enterprise WAN and security work across finance, telecom and defence, and I hold Google Cloud Professional Cloud Network Engineer, Azure Network Engineer Associate, CCNA and CCNP certifications.
