About Sanjay Singh Rajput
Network Architect – Cloud & Security with over 10 years of experience designing, implementing, securing, and automating enterprise-scale networks across on-premise, data center, and hybrid cloud environments. I specialize in network architecture, cloud networking, SD-WAN, SASE, Zero Trust, and network security, delivering scalable, resilient, and compliant solutions aligned with business objectives. Currently at Persistent Systems, I architect and manage hybrid cloud and Azure networking solutions supporting SaaS and PaaS platforms, lead SD-WAN and SASE initiatives, and collaborate closely with Cloud, DevOps, and Security teams to design high-availability, performance-driven architectures. My technical expertise includes routing and switching technologies such as BGP, OSPF, EIGRP, MPLS, VXLAN, VRF, enterprise data center networking using Cisco Nexus, and WAN transformation using Cisco Viptela. I have strong hands-on experience with network security technologies including Palo Alto, Fortinet, Cisco ASA and Firepower, Zscaler ZIA, ZPA, and ZDX, along with IPsec and SSL VPN architectures, firewall policy design, network segmentation, and Zero Trust implementation. Automation is a key part of my approach, and I actively use Python with Netmiko, NAPALM, and REST APIs to automate configuration backups, compliance checks, inventory management, and audit reporting, helping reduce manual effort, improve consistency, and enhance operational efficiency. Previously, I have delivered enterprise networking and security solutions at HCL Technologies, Accenture, and Tata Consultancy Services, supporting global clients across large-scale environments with SD-WAN migrations, cloud security integrations, data center operations, and advanced L3 troubleshooting. My focus areas include Cloud Networking, Network Architecture, Network Security, SD-WAN, SASE, Zero Trust, Azure Networking, Hybrid Cloud, Firewall Architecture, Automation, and enterprise-grade infrastructure design, and I am open to Network Architect, Cloud Network Architect, and Security Architect roles.
