I’m a results-driven Network Planning & Optimization Specialist with 15+ years of experience designing, planning, optimizing, and operating complex network architectures for Service Providers, Enterprises, and Data Centers.

Since Apr 2019, I’ve designed and optimized scalable Leaf-Spine/Clos environments at Nokia, delivering HLD/LLD documentation and partnering with cross-functional teams to ensure smooth implementation aligned with business needs. I also serve as a Level 3 escalation point for complex MPLS VPN and Data Centre network issues, driving troubleshooting and optimization for BGP, ISIS, OSPF, VPLS, VPRN, and LACP.

Previously at Orange Business Services, I managed configuration, deployment, and migration of MPLS VPN sites for aviation clients, supported global airline projects, and implemented design and process improvements that reduced service disruptions while improving reliability for business-critical customers.

Earlier at Tata Consultancy Services and Alcatel-Lucent/Reliance Communications, I maintained enterprise networks, handled firewalls and F5 load balancers, and used tools like Wireshark, SolarWinds, and NetFlow for root cause analysis and timely issue resolution—helping me build a consistent ethos of reliability, RCA-led improvement, and clear documentation. I’m also pursuing CCIE Service Provider (Apr 2026) and hold a Cisco Certified Specialist – Service Provider Core (Jan 2025).
