Hyderabad, Telangana, India
I am a Lead Network Engineer with more than 10 years of experience in enterprise network engineering, specializing in designing, implementing, and transforming large scale network infrastructures across multi site environments. My career has evolved from hands on network support roles into advanced network design, architecture, and transformation leadership positions. I work across the full network lifecycle, starting from requirement analysis and infrastructure assessment, moving into HLD and LLD design, followed by procurement coordination, implementation, migration planning, and post deployment hypercare support. I focus on translating complex business and technical requirements into scalable, secure, and reliable network solutions that support business continuity and growth. My core expertise includes enterprise LAN and WAN design, routing and switching using Cisco technologies, and wireless infrastructure deployment using Cisco 9800 Wireless LAN Controllers. I have hands on experience in building and managing enterprise Wi Fi environments including secure authentication based access, AP onboarding, RF surveys, heat map analysis, and wireless optimization to ensure strong coverage and performance. In network security and access control, I have worked with Cisco ISE for endpoint profiling, policy enforcement, and secure access management across wired and wireless networks. I also have exposure to Fortinet and Sophos firewalls, along with VPN configuration and segmentation strategies that enhance enterprise security posture. One of my key strengths is SD WAN migration experience across multi site environments, where I have contributed to zero downtime transitions by coordinating with stakeholders, vendors, and internal teams. This has strengthened my ability in change management, risk control, and structured deployment execution. I also have strong experience in IP address management using Infoblox DDI, ensuring proper DHCP management, structured IP allocation, and elimination of IP conflicts across distributed networks. Alongside this, I have worked on IoT and specialized device integration, enabling secure and reliable connectivity for enterprise devices in healthcare, smart infrastructure, and facility environments. I am currently looking for new opportunities in the UAE where I can apply my expertise in enterprise network transformation, multi site infrastructure, SD WAN, wireless engineering, and network security in large scale and complex environments.
